SYNOPSIS
 

#include &#60;pcre2.h&#62;


int pcre2_substring_number_from_name(const pcre2_code *code,
 PCRE2_SPTR name);

 
DESCRIPTION
 

This convenience function finds the number of a named substring capturing
parenthesis in a compiled pattern, provided that it is a unique name. The
function arguments are:
<pre>
 code Compiled regular expression
 name Name whose number is required
</pre>
The yield of the function is the number of the parenthesis if the name is
found, or PCRE2_ERROR_NOSUBSTRING if it is not found. When duplicate names are
allowed (PCRE2_DUPNAMES is set), if the name is not unique,
PCRE2_ERROR_NOUNIQUESUBSTRING is returned. You can obtain the list of numbers
with the same name by calling pcre2_substring_nametable_scan().


There is a complete description of the PCRE2 native API in the
<a href="pcre2api.html">pcre2api</a>
page and a description of the POSIX API in the
