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


       This convenience function finds the number of a named substring captur-
       ing 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_get_stringnumber().  You can obtain the complete
       list by calling pcre_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.
