SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>int pcre2_substring_number_from_name(const pcre2_code *<i>code</i>,</b>
<b>  PCRE2_SPTR <i>name</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
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>
  <i>code</i>    Compiled regular expression
  <i>name</i>    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 <b>pcre2_substring_nametable_scan()</b>.
