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>
|
|
<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>.
