.TH PCRE_COPY_NAMED_SUBSTRING 3 "24 June 2012" "PCRE 8.30"
.SH NAME

.B int pcre_copy_named_substring(const pcre *\fIcode\fP,
.B " const char *\fIsubject\fP, int *\fIovector\fP,"

.sp
.B int pcre16_copy_named_substring(const pcre16 *\fIcode\fP,
.B " PCRE_SPTR16 \fIsubject\fP, int *\fIovector\fP,"
.B " int \fIstringcount\fP, PCRE_SPTR16 \fIstringname\fP,"

.SH DESCRIPTION
.rs
.sp
This is a convenience function for extracting a captured substring, identified
by name, into a given buffer. The arguments are:
.sp
\fIcode\fP Pattern that was successfully matched
\fIsubject\fP Subject that has been successfully matched
\fIovector\fP Offset vector that \fBpcre[16|32]_exec()\fP used
\fIstringcount\fP Value returned by \fBpcre[16|32]_exec()\fP
\fIstringname\fP Name of the required substring
\fIbuffer\fP Buffer to receive the string
\fIbuffersize\fP Size of buffer
.sp
The yield is the length of the substring, PCRE_ERROR_NOMEMORY if the buffer was
too small, or PCRE_ERROR_NOSUBSTRING if the string name is invalid.
.P
There is a complete description of the PCRE native API in the
.\" HREF
\fBpcreapi\fP
.\"
page and a description of the POSIX API in the
.\" HREF
\fBpcreposix\fP
.\"
page.
