       PCRE - Perl-compatible regular expressions


       #include <pcre.h>

       int pcre_get_stringtable_entries(const pcre *code,
            const char *name, char **first, char **last);


       This  convenience function finds, for a compiled pattern, the first and
       last entries for a given name in the table  that  translates  capturing
       parenthesis  names  into  numbers. When names are required to be unique
       (PCRE_DUPNAMES  is  not   set),   it   is   usually   easier   to   use
       pcre_get_stringnumber() instead.

         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

       The   yield   of   the  function  is  the  length  of  each  entry,  or
       PCRE_ERROR_NOSUBSTRING if none are found.

       There is a complete description of the PCRE native API,  including  the
       format  of the table entries, in the pcreapi page, and a description of
       the POSIX API in the pcreposix page.
