PCRE2 - Perl-compatible regular expressions (revised API)

.SH SYNOPSIS

.rs

|

.SH DESCRIPTION
|

|
|
.rs
|
||
|
|
.sp
|
||
|
|
This convenience function finds, for a compiled pattern, the first and last
|
||
|
|
entries for a given name in the table that translates capture group names into
|
||
|
|
numbers.
|
||
|
|
.sp
|
||
|
|
\fIcode\fP Compiled regular expression
|
||
|
|
\fIname\fP Name whose entries required
|
||
|
|
\fIfirst\fP Where to return a pointer to the first entry
|
||
|
|
\fIlast\fP Where to return a pointer to the last entry
|
||
|
|
.sp
|
||
|
|
When the name is found in the table, if \fIfirst\fP is NULL, the function
|
||
|
|
returns a group number, but if there is more than one matching entry, it is not
|
||
|
|
defined which one. Otherwise, when both pointers have been set, the yield of
|
||
|
|
the function is the length of each entry in code units. If the name is not
|
||
|
|
found, PCRE2_ERROR_NOSUBSTRING is returned.
