       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int pcre_get_stringnumber(const pcre *code,
            const char *name);

       int pcre16_get_stringnumber(const pcre16 *code,
            PCRE_SPTR16 name);

       int pcre32_get_stringnumber(const pcre32 *code,
            PCRE_SPTR32 name);

DESCRIPTION

       This convenience function finds the number of a named substring capturing parenthesis in a
       compiled pattern. Its arguments are:

         code    Compiled regular expression
         name    Name whose number is required

       The yield of the function is the number of the  parenthesis  if  the  name  is  found,  or
       PCRE_ERROR_NOSUBSTRING otherwise. When duplicate names are allowed (PCRE_DUPNAMES is set),
       it is not defined which of the numbers is returned by pcre[16|32]_get_stringnumber().  You
       can obtain the complete list by calling pcre[16|32]_get_stringtable_entries().

       There  is  a  complete  description  of  the  PCRE  native  API  in the pcreapi page and a
       description of the POSIX API in the pcreposix page.
