SYNOPSIS
 

#include &#60;pcre.h&#62;


int pcre_copy_named_substring(const pcre *code,
const char *subject, int *ovector,
int stringcount, const char *stringname,
char *buffer, int buffersize);


int pcre16_copy_named_substring(const pcre16 *code,
PCRE_SPTR16 subject, int *ovector,
int stringcount, PCRE_SPTR16 stringname,
PCRE_UCHAR16 *buffer, int buffersize);


int pcre32_copy_named_substring(const pcre32 *code,
PCRE_SPTR32 subject, int *ovector,
int stringcount, PCRE_SPTR32 stringname,
PCRE_UCHAR32 *buffer, int buffersize);

 
DESCRIPTION
 

This is a convenience function for extracting a captured substring, identified
by name, into a given buffer. The arguments are:
<pre>
 code Pattern that was successfully matched
 subject Subject that has been successfully matched
 ovector Offset vector that pcre[16|32]_exec() used
 stringcount Value returned by pcre[16|32]_exec()
 stringname Name of the required substring
 buffer Buffer to receive the string
 buffersize Size of buffer
</pre>
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.


There is a complete description of the PCRE native API in the
<a href="pcreapi.html">pcreapi</a>
page and a description of the POSIX API in the
<a href="pcreposix.html">pcreposix</a>
