|
|
|
<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:
|
|
<P>
|
|
<BR> <I>code</I> Compiled regular expression
|
|
<BR> <I>name</I> Name whose number is required
|
|
<P>
|
|
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>.
|
|
<P>
|
|
|
|
There is a complete description of the PCRE2 native API in the
|

<B>pcre2api</B>
|
|
|
|
page and a description of the POSIX API in the
