posix_spawnattr_setsigdefault

       set  the  spawn-sigdefault  attribute  of  a  spawn  attributes  object
       (ADVANCED REALTIME)

SYNOPSIS
       #include <signal.h>
       #include <spawn.h>

       int posix_spawnattr_getsigdefault(const posix_spawnattr_t *
              restrict attr, sigset_t *restrict sigdefault);
       int posix_spawnattr_setsigdefault(posix_spawnattr_t *restrict attr,
              const sigset_t *restrict sigdefault);


DESCRIPTION
       The  posix_spawnattr_getsigdefault() function shall obtain the value of
       the spawn-sigdefault attribute from the attributes object referenced by
       attr.

       The posix_spawnattr_setsigdefault() function shall set the spawn-sigde-
       fault attribute in an initialized attributes object referenced by attr.

       The spawn-sigdefault attribute represents the  set  of  signals  to  be
       forced  to  default  signal  handling  in  the  new  process  image (if
       POSIX_SPAWN_SETSIGDEF is set in the spawn-flags attribute) by  a  spawn
       operation. The default value of this attribute shall be an empty signal
       set.

RETURN VALUE
       Upon  successful  completion,   posix_spawnattr_getsigdefault()   shall
       return  zero  and  store the value of the spawn-sigdefault attribute of
       attr into the object referenced by the sigdefault parameter; otherwise,
       an error number shall be returned to indicate the error.

       Upon   successful   completion,  posix_spawnattr_setsigdefault()  shall
       return zero; otherwise, an error number shall be returned  to  indicate
       the error.

ERRORS
       These functions may fail if:

       EINVAL The value specified by attr is invalid.


       The posix_spawnattr_setsigdefault() function may fail if:

       EINVAL The value of the attribute being set is not valid.
