       Perl functions

DESCRIPTION
       This file is the autogenerated documentation of functions in the Perl
       interpreter that are documented using Perl's internal documentation
       format but are not marked as part of the Perl API. In other words, they
       are not for use in extensions!

Compile-time scope hooks
       BhkENTRY
               Return an entry from the BHK structure. which is a preprocessor
               token indicating which entry to return. If the appropriate flag
               is not set this will return NULL. The type of the return value
               depends on which entry you ask for.

               NOTE: this function is experimental and may change or be
               removed without notice.

                       void *  BhkENTRY(BHK *hk, which)

       BhkFLAGS
               Return the BHK's flags.

               NOTE: this function is experimental and may change or be
               removed without notice.

                       U32     BhkFLAGS(BHK *hk)

       CALL_BLOCK_HOOKS
               Call all the registered block hooks for type which. which is a
               preprocessing token; the type of arg depends on which.

               NOTE: this function is experimental and may change or be
               removed without notice.

                       void    CALL_BLOCK_HOOKS(which, arg)

CV reference counts and CvOUTSIDE
       CvWEAKOUTSIDE
               Each CV has a pointer, "CvOUTSIDE()", to its lexically
               enclosing CV (if any). Because pointers to anonymous sub
               prototypes are stored in "&" pad slots, it is a possible to get
               a circular reference, with the parent pointing to the child and
               vice-versa. To avoid the ensuing memory leak, we do not
               increment the reference count of the CV pointed to by
               "CvOUTSIDE" in the one specific instance that the parent has a
               "&" pad slot pointing back to us. In this case, we set the
               "CvWEAKOUTSIDE" flag in the child. This allows us to determine
               under what circumstances we should decrement the refcount of
               the parent when freeing the child.

               There is a further complication with non-closure anonymous subs
               (i.e. those that do not refer to any lexicals outside that
               sub). In this case, the anonymous prototype is shared rather

               To avoid this, whenever a CV and its associated pad is freed,
               any "&" entries in the pad are explicitly removed from the pad,
               and if the refcount of the pointed-to anon sub is still
               positive, then that child's "CvOUTSIDE" is set to point to its
               grandparent. This will only occur in the single specific case
               of a non-closure anon prototype having one or more active
               references (such as $a above).

               One other thing to consider is that a CV may be merely
               undefined rather than freed, eg "undef &foo". In this case, its
               refcount may not have reached zero, but we still delete its pad
               and its "CvROOT" etc.  Since various children may still have
               their "CvOUTSIDE" pointing at this undefined CV, we keep its
               own "CvOUTSIDE" for the time being, so that the chain of
               lexical scopes is unbroken. For example, the following should
               print 123:

                   my $x = 123;
                   sub tmp { sub { eval '$x' } }
                   my $a = tmp();
                   undef &tmp;
                   print  $a->();

                       bool    CvWEAKOUTSIDE(CV *cv)

Embedding Functions
       cv_dump dump the contents of a CV

                       void    cv_dump(CV *cv, const char *title)

       cv_forget_slab
               When a CV has a reference count on its slab (CvSLABBED), it is
               responsible for making sure it is freed.  (Hence, no two CVs
               should ever have a reference count on the same slab.)  The CV
               only needs to reference the slab during compilation.  Once it
               is compiled and CvROOT attached, it has finished its job, so it
               can forget the slab.

                       void    cv_forget_slab(CV *cv)

       do_dump_pad
               Dump the contents of a padlist

                       void    do_dump_pad(I32 level, PerlIO *file,
                                           PADLIST *padlist, int full)

       intro_my
               "Introduce" my variables to visible status.  This is called
               during parsing at the end of each statement to make lexical
               variables visible to subsequent statements.

                       U32     intro_my()

               namesv.  None of the other processing of "pad_add_name_pvn" in
               perlapi is done.  Returns the offset of the allocated pad slot.

                       PADOFFSET pad_alloc_name(SV *namesv, U32 flags,
                                                HV *typestash, HV *ourstash)

       pad_block_start
               Update the pad compilation state variables on entry to a new
               block.

                       void    pad_block_start(int full)

       pad_check_dup
               Check for duplicate declarations: report any of:

                    * a my in the current scope with the same name;
                    * an our (anywhere in the pad) with the same name and the
                      same stash as C<ourstash>

               "is_our" indicates that the name to check is an 'our'
               declaration.

                       void    pad_check_dup(SV *name, U32 flags,
                                             const HV *ourstash)

       pad_findlex
               Find a named lexical anywhere in a chain of nested pads. Add
               fake entries in the inner pads if it's found in an outer one.

               Returns the offset in the bottom pad of the lex or the fake
               lex.  cv is the CV in which to start the search, and seq is the
               current cop_seq to match against. If warn is true, print
               appropriate warnings.  The out_* vars return values, and so are
               pointers to where the returned values should be stored.
               out_capture, if non-null, requests that the innermost instance
               of the lexical is captured; out_name_sv is set to the innermost
               matched namesv or fake namesv; out_flags returns the flags
               normally associated with the IVX field of a fake namesv.

               Note that pad_findlex() is recursive; it recurses up the chain
               of CVs, then comes back down, adding fake entries as it goes.
               It has to be this way because fake namesvs in anon protoypes
               have to store in xlow the index into the parent pad.

                       PADOFFSET pad_findlex(const char *namepv,
                                             STRLEN namelen, U32 flags,
                                             const CV* cv, U32 seq, int warn,
                                             SV** out_capture,
                                             SV** out_name_sv, int *out_flags)

       pad_fixup_inner_anons
               For any anon CVs in the pad, change CvOUTSIDE of that CV from
               old_cv to new_cv if necessary. Needed when a newly-compiled CV
               has to be moved to a pre-existing CV struct.
               never got introduced.

                       void    pad_leavemy()

       pad_push
               Push a new pad frame onto the padlist, unless there's already a
               pad at this depth, in which case don't bother creating a new
               one.  Then give the new pad an @_ in slot zero.

                       void    pad_push(PADLIST *padlist, int depth)

       pad_reset
               Mark all the current temporaries for reuse

                       void    pad_reset()

       pad_swipe
               Abandon the tmp in the current pad at offset po and replace
               with a new one.

                       void    pad_swipe(PADOFFSET po, bool refadjust)

Functions in file op.c
       core_prototype
               This function assigns the prototype of the named core function
               to "sv", or to a new mortal SV if "sv" is NULL.  It returns the
               modified "sv", or NULL if the core function has no prototype.
               "code" is a code as returned by "keyword()".  It must not be
               equal to 0 or -KEY_CORE.

                       SV *    core_prototype(SV *sv, const char *name,
                                              const int code,
                                              int * const opnum)

Functions in file pp_ctl.c
       docatch Check for the cases 0 or 3 of cur_env.je_ret, only used inside
               an eval context.

               0 is used as continue inside eval,

               3 is used for a die caught by an inner eval - continue inner
               loop

               See cop.h: je_mustcatch, when set at any runlevel to TRUE,
               means eval ops must establish a local jmpenv to handle
               exception traps.

                       OP*     docatch(OP *o)

GV Functions
       gv_try_downgrade
               If the typeglob "gv" can be expressed more succinctly, by
               having something other than a real GV in its place in the
               stash, replace it with the optimised form.  Basic requirements
               placeholder that more compactly represents the same thing.

               NOTE: this function is experimental and may change or be
               removed without notice.

                       void    gv_try_downgrade(GV* gv)

Hash Manipulation Functions
       hv_ename_add
               Adds a name to a stash's internal list of effective names.  See
               "hv_ename_delete".

               This is called when a stash is assigned to a new location in
               the symbol table.

                       void    hv_ename_add(HV *hv, const char *name, U32 len,
                                            U32 flags)

       hv_ename_delete
               Removes a name from a stash's internal list of effective names.
               If this is the name returned by "HvENAME", then another name in
               the list will take its place ("HvENAME" will use it).

               This is called when a stash is deleted from the symbol table.

                       void    hv_ename_delete(HV *hv, const char *name,
                                               U32 len, U32 flags)

       refcounted_he_chain_2hv
               Generates and returns a "HV *" representing the content of a
               "refcounted_he" chain.  flags is currently unused and must be
               zero.

                       HV *    refcounted_he_chain_2hv(
                                   const struct refcounted_he *c, U32 flags
                               )

       refcounted_he_fetch_pv
               Like "refcounted_he_fetch_pvn", but takes a nul-terminated
               string instead of a string/length pair.

                       SV *    refcounted_he_fetch_pv(
                                   const struct refcounted_he *chain,
                                   const char *key, U32 hash, U32 flags
                               )

       refcounted_he_fetch_pvn
               Search along a "refcounted_he" chain for an entry with the key
               specified by keypv and keylen.  If flags has the
               "REFCOUNTED_HE_KEY_UTF8" bit set, the key octets are
               interpreted as UTF-8, otherwise they are interpreted as
               Latin-1.  hash is a precomputed hash of the key string, or zero
               if it has not been precomputed.  Returns a mortal scalar
               representing the value associated with the key, or

                       SV *    refcounted_he_fetch_pvs(
                                   const struct refcounted_he *chain,
                                   const char *key, U32 flags
                               )

       refcounted_he_fetch_sv
               Like "refcounted_he_fetch_pvn", but takes a Perl scalar instead
               of a string/length pair.

                       SV *    refcounted_he_fetch_sv(
                                   const struct refcounted_he *chain, SV *key,
                                   U32 hash, U32 flags
                               )

       refcounted_he_free
               Decrements the reference count of a "refcounted_he" by one.  If
               the reference count reaches zero the structure's memory is
               freed, which (recursively) causes a reduction of its parent
               "refcounted_he"'s reference count.  It is safe to pass a null
               pointer to this function: no action occurs in this case.

                       void    refcounted_he_free(struct refcounted_he *he)

       refcounted_he_inc
               Increment the reference count of a "refcounted_he".  The
               pointer to the "refcounted_he" is also returned.  It is safe to
               pass a null pointer to this function: no action occurs and a
               null pointer is returned.

                       struct refcounted_he * refcounted_he_inc(
                                                  struct refcounted_he *he
                                              )

       refcounted_he_new_pv
               Like "refcounted_he_new_pvn", but takes a nul-terminated string
               instead of a string/length pair.

                       struct refcounted_he * refcounted_he_new_pv(
                                                  struct refcounted_he *parent,
                                                  const char *key, U32 hash,
                                                  SV *value, U32 flags
                                              )

       refcounted_he_new_pvn
               Creates a new "refcounted_he".  This consists of a single
               key/value pair and a reference to an existing "refcounted_he"
               chain (which may be empty), and thus forms a longer chain.
               When using the longer chain, the new key/value pair takes
               precedence over any entry for the same key further along the
               chain.

               The new key is specified by keypv and keylen.  If flags has the
               "REFCOUNTED_HE_KEY_UTF8" bit set, the key octets are
               takes precedence over the existence of a value for the key
               further along the chain.

               parent points to the rest of the "refcounted_he" chain to be
               attached to the new "refcounted_he".  This function takes
               ownership of one reference to parent, and returns one reference
               to the new "refcounted_he".

                       struct refcounted_he * refcounted_he_new_pvn(
                                                  struct refcounted_he *parent,
                                                  const char *keypv,
                                                  STRLEN keylen, U32 hash,
                                                  SV *value, U32 flags
                                              )

       refcounted_he_new_pvs
               Like "refcounted_he_new_pvn", but takes a literal string
               instead of a string/length pair, and no precomputed hash.

                       struct refcounted_he * refcounted_he_new_pvs(
                                                  struct refcounted_he *parent,
                                                  const char *key, SV *value,
                                                  U32 flags
                                              )

       refcounted_he_new_sv
               Like "refcounted_he_new_pvn", but takes a Perl scalar instead
               of a string/length pair.

                       struct refcounted_he * refcounted_he_new_sv(
                                                  struct refcounted_he *parent,
                                                  SV *key, U32 hash, SV *value,
                                                  U32 flags
                                              )

IO Functions
       start_glob
               Function called by "do_readline" to spawn a glob (or do the
               glob inside perl on VMS). This code used to be inline, but now
               perl uses "File::Glob" this glob starter is only used by
               miniperl during the build process.  Moving it away shrinks
               pp_hot.c; shrinking pp_hot.c helps speed perl up.

               NOTE: this function is experimental and may change or be
               removed without notice.

                       PerlIO* start_glob(SV *tmpglob, IO *io)

Magical Functions
       magic_clearhint
               Triggered by a delete from %^H, records the key to
               "PL_compiling.cop_hints_hash".

                       int     magic_clearhint(SV* sv, MAGIC* mg)

               "meth" is the name of the method to call.

               "argc" is the number of args (in addition to $self) to pass to
               the method.

               The "flags" can be:

                   G_DISCARD     invoke method with G_DISCARD flag and don't
                                 return a value
                   G_UNDEF_FILL  fill the stack with argc pointers to
                                 PL_sv_undef

               The arguments themselves are any values following the "flags"
               argument.

               Returns the SV (if any) returned by the method, or NULL on
               failure.

                       SV*     magic_methcall(SV *sv, const MAGIC *mg,
                                              const char *meth, U32 flags,
                                              U32 argc, ...)

       magic_sethint
               Triggered by a store to %^H, records the key/value pair to
               "PL_compiling.cop_hints_hash".  It is assumed that hints aren't
               storing anything that would need a deep copy.  Maybe we should
               warn if we find a reference.

                       int     magic_sethint(SV* sv, MAGIC* mg)

       mg_localize
               Copy some of the magic from an existing SV to new localized
               version of that SV. Container magic (eg %ENV, $1, tie) gets
               copied, value magic doesn't (eg taint, pos).

               If setmagic is false then no set magic will be called on the
               new (empty) SV.  This typically means that assignment will soon
               follow (e.g. 'local $x = $y'), and that will handle the magic.

                       void    mg_localize(SV* sv, SV* nsv, bool setmagic)

MRO Functions
       mro_get_linear_isa_dfs
               Returns the Depth-First Search linearization of @ISA the given
               stash.  The return value is a read-only AV*.  "level" should be
               0 (it is used internally in this function's recursion).

               You are responsible for "SvREFCNT_inc()" on the return value if
               you plan to store it anywhere semi-permanently (otherwise it
               might be deleted out from under you the next time the cache is
               invalidated).

                       AV*     mro_get_linear_isa_dfs(HV* stash, U32 level)

               assigned to.

               This can also be called with a null first argument to indicate
               that "oldstash" has been deleted.

               This function invalidates isa caches on the old stash, on all
               subpackages nested inside it, and on the subclasses of all
               those, including non-existent packages that have corresponding
               entries in "stash".

               It also sets the effective names ("HvENAME") on all the stashes
               as appropriate.

               If the "gv" is present and is not in the symbol table, then
               this function simply returns.  This checked will be skipped if
               "flags & 1".

                       void    mro_package_moved(HV * const stash,
                                                 HV * const oldstash,
                                                 const GV * const gv,
                                                 U32 flags)

Optree Manipulation Functions
       finalize_optree
               This function finalizes the optree. Should be called directly
               after the complete optree is built. It does some additional
               checking which can't be done in the normal ck_xxx functions and
               makes the tree thread-safe.

                       void    finalize_optree(OP* o)

Pad Data Structures

                       U32     PAD_COMPNAME_FLAGS(PADOFFSET po)

       PAD_COMPNAME_GEN
               The generation number of the name at offset "po" in the current
               compiling pad (lvalue). Note that "SvUVX" is hijacked for this
               purpose.

                       STRLEN  PAD_COMPNAME_GEN(PADOFFSET po)

       PAD_COMPNAME_GEN_set
               Sets the generation number of the name at offset "po" in the
               current ling pad (lvalue) to "gen".  Note that "SvUV_set" is
               hijacked for this purpose.

                       STRLEN  PAD_COMPNAME_GEN_set(PADOFFSET po, int gen)

       PAD_COMPNAME_OURSTASH
               Return the stash associated with an "our" variable.  Assumes

               offset "po". Must be a valid name. Returns null if not typed.

                       HV *    PAD_COMPNAME_TYPE(PADOFFSET po)

               PAD_SAVE_LOCAL()

                       void    PAD_SAVE_LOCAL(PAD *opad, PAD *npad)

       PAD_SAVE_SETNULLPAD
               Save the current pad then set it to null.

                       void    PAD_SAVE_SETNULLPAD()

       PAD_SETSV
               Set the slot at offset "po" in the current pad to "sv"

       PAD_SET_CUR
               Set the current pad to be pad "n" in the padlist, saving the
               previous current pad. NB currently this macro expands to a
               string too long for some compilers, so it's best to replace it
               with

                   SAVECOMPPAD();
                   PAD_SET_CUR_NOSAVE(padlist,n);


                       void    PAD_SET_CUR(PADLIST padlist, I32 n)

       PAD_SET_CUR_NOSAVE

                       void    SAVECLEARSV(SV **svp)

       SAVECOMPPAD
               When Perl is run in debugging mode, with the -d switch, this SV
               is a boolean which indicates whether subs are being single-
               stepped.  Single-stepping is automatically turned on after
               every step.  This is the C variable which corresponds to Perl's
               $DB::single variable.  See "PL_DBsub".

                       SV *    PL_DBsingle

       PL_DBsub
               When Perl is run in debugging mode, with the -d switch, this GV
               contains the SV which holds the name of the sub being debugged.
               This is the C variable which corresponds to Perl's $DB::sub
               variable.  See "PL_DBsingle".

                       GV *    PL_DBsub

       PL_DBtrace
               Trace variable used when Perl is run in debugging mode, with
               the -d switch.  This is the C variable which corresponds to
               Perl's $DB::trace variable.  See "PL_DBsingle".

                       SV *    PL_DBtrace

       PL_dowarn
               The C variable which corresponds to Perl's $^W warning
               variable.

                       bool    PL_dowarn

       PL_last_in_gv
               The GV which was last used for a filehandle input operation.
               ("<FH>")

                       GV*     PL_last_in_gv

       PL_ofsgv
               The glob containing the output field separator - "*," in Perl
               space.

                       GV*     PL_ofsgv

       PL_rs   The input record separator - $/ in Perl space.

                       SV*     PL_rs

Stack Manipulation Macros
       djSP    Declare Just "SP". This is actually identical to "dSP", and
               declares a local copy of perl's stack pointer, available via
               the "SP" macro.  See "SP".  (Available for backward source code
               compatibility with the old (Perl 5.005) thread model.)

                               djSP;

       LVRET   True if this op will be the return value of an lvalue
               This is used internally by various sv-modifying functions, such
               as sv_setsv, sv_setiv and sv_pvn_force.

               One case that this does not handle is a gv without SvFAKE set.
               After

                   if (SvTHINKFIRST(gv)) sv_force_normal(gv);

               it will still be a gv.

               SvTHINKFIRST sometimes produces false positives.  In those
               cases sv_force_normal does nothing.

                       U32     SvTHINKFIRST(SV *sv)

       sv_add_arena
               Given a chunk of memory, link it to the head of the list of
               arenas, and split it into a list of free SVs.

                       void    sv_add_arena(char *const ptr, const U32 size,
                                            const U32 flags)

       sv_clean_all
               Decrement the refcnt of each remaining SV, possibly triggering
               a cleanup.  This function may have to be called multiple times
               to free SVs which are in complex self-referential hierarchies.

                       I32     sv_clean_all()

       sv_clean_objs
               Attempt to destroy all objects not yet freed.

                       void    sv_clean_objs()

       sv_free_arenas
               Deallocate the memory used by all arenas.  Note that all the
               individual SV heads and bodies within the arenas must already
               have been freed.

                       void    sv_free_arenas()

SV-Body Allocation
       sv_2num Return an SV with the numeric value of the source SV, doing any
               necessary reference or overload conversion.  You must use the
               "SvNUM(sv)" macro to access this function.

               NOTE: this function is experimental and may change or be
               removed without notice.

                       SV*     sv_2num(SV *const sv)

       sv_copypv
               Copies a stringified representation of the source SV into the
               destination SV.  Automatically performs any necessary mg_get
                                      const int ob)

Unicode Support
       find_uninit_var
               Find the name of the undefined variable (if any) that caused
               the operator to issue a "Use of uninitialized value" warning.
               If match is true, only return a name if its value matches
               uninit_sv.  So roughly speaking, if a unary operator (such as
               OP_COS) generates a warning, then following the direct child of
               the op may yield an OP_PADSV or OP_GV that gives the name of
               the undefined variable.  On the other hand, with OP_ADD there
               are two branches to follow, so we only print the variable name
               if we get an exact match.

               The name is returned as a mortal SV.

               Assumes that PL_op is the op that originally triggered the
               error, and that PL_comppad/PL_curpad points to the currently
               executing pad.

               NOTE: this function is experimental and may change or be
               removed without notice.

                       SV*     find_uninit_var(const OP *const obase,
                                               const SV *const uninit_sv,
                                               bool top)

       report_uninit
               Print appropriate "Use of uninitialized variable" warning.

                       void    report_uninit(const SV *uninit_sv)
