| 14 | .SH DESCRIPTION |
| 15 | .rs |
| 16 | .sp |
| 17 | This convenience function finds the number of a named substring capturing |
| 18 | parenthesis in a compiled pattern, provided that it is a unique name. The |
| 19 | function arguments are: |
| 20 | .sp |
| 21 | \fIcode\fP Compiled regular expression |
| 22 | \fIname\fP Name whose number is required |
| 23 | .sp |
| 24 | The yield of the function is the number of the parenthesis if the name is |
| 25 | found, or PCRE2_ERROR_NOSUBSTRING if it is not found. When duplicate names are |
| 26 | allowed (PCRE2_DUPNAMES is set), if the name is not unique, |
| 27 | PCRE2_ERROR_NOUNIQUESUBSTRING is returned. You can obtain the list of numbers |
| 28 | with the same name by calling \fBpcre2_substring_nametable_scan()\fP. |
