DESCRIPTION
</b><br>
<P>
This convenience function finds the number of a named substring capturing
parenthesis in a compiled pattern. Its 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 otherwise. When duplicate names are allowed
(PCRE2_DUPNAMES is set), it is not defined which of the numbers is returned.
You can obtain the complete list by calling
<b>pcre2_substring_nametable_scan()</b>.
