.rs
|

.sp
|
| 21 |
This convenience function finds the number of a named substring capturing
|
| 22 |
parenthesis in a compiled pattern. Its arguments are:
|
| 23 |
.sp
|
| 24 |
\fIcode\fP Compiled regular expression
|
| 25 |
\fIname\fP Name whose number is required
|
| 26 |
.sp
|
| 27 |
The yield of the function is the number of the parenthesis if the name is
|
| 28 |
found, or PCRE_ERROR_NOSUBSTRING otherwise. When duplicate names are allowed
|
| 29 |
(PCRE_DUPNAMES is set), it is not defined which of the numbers is returned by
|
| 30 |
\fBpcre[16]_get_stringnumber()\fP. You can obtain the complete list by calling
|
| 31 |
\fBpcre[16]_get_stringtable_entries()\fP.
