PCRE2 - Perl-compatible regular expressions (revised API)


       #include <pcre2.h>

       int pcre2_substring_nametable_scan(const pcre2_code *code,
         PCRE2_SPTR name, PCRE2_SPTR *first, PCRE2_SPTR *last);


       This  convenience function finds, for a compiled pattern, the first and
       last entries for a given name in  the  table  that  translates  capture
       group names into numbers.

         code    Compiled regular expression
         name    Name whose entries required
         first   Where to return a pointer to the first entry
         last    Where to return a pointer to the last entry

       When  the  name  is  found in the table, if first is NULL, the function
       returns a group number, but if there is more than one  matching  entry,
       it  is  not  defined which one. Otherwise, when both pointers have been
       set, the yield of the function is the length  of  each  entry  in  code
       units. If the name is not found, PCRE2_ERROR_NOSUBSTRING is returned.

       There  is a complete description of the PCRE2 native API, including the
       format of the table entries, in the pcre2api page, and a description of
       the POSIX API in the pcre2posix page.
