| .SH NAME |
| PCRE2 - Perl-compatible regular expressions (revised API) |
| .SH SYNOPSIS |
| .rs |
| .sp |
| .B #include <pcre2.h> |
| .PP |
| .nf |
| .B int pcre2_substring_number_from_name(const pcre2_code *\fIcode\fP, |
| .B " PCRE2_SPTR \fIname\fP);" |
| .fi |
| . |
| .SH DESCRIPTION |
| .rs |
| .sp |
| 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: |
| .sp |
| \fIcode\fP Compiled regular expression |
| \fIname\fP Name whose number is required |
| .sp |
| 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 \fBpcre2_substring_nametable_scan()\fP. |
