SYNOPSIS
#include <pcre.h>
int pcre_get_stringnumber(const pcre *code,
const char *name);

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.
