PCRE - Perl-compatible regular expressions

.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 capturing parenthesis
|
|
names into numbers. When names are required to be unique (PCRE_DUPNAMES is
|
|
\fInot\fP set), it is usually easier to use \fBpcre[16|32]_get_stringnumber()\fP
|
|
instead.
|
|
.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
|
|
The yield of the function is the length of each entry, or
|
|
PCRE_ERROR_NOSUBSTRING if none are found.
|
|

There is a complete description of the PCRE native API, including the format of
|
|
the table entries, in the
|
|
.\" HREF
|
|
\fBpcreapi\fP
|
|
.\"
|
|
page, and a description of the POSIX API in the
|
|
.\" HREF
|
|
\fBpcreposix\fP
|

|
|
page.
