PCRE_GET_STRINGTABLE_ENTRIES(3) 			     Library Functions Manual				   PCRE_GET_STRINGTABLE_ENTRIES(3)

NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

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

DESCRIPTION

       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.
