<P>
<b>#include &#60;pcre.h&#62;</b>

<P>
<b>int pcre_copy_named_substring(const pcre *<i>code</i>,</b>
<b>const char *<i>subject</i>, int *<i>ovector</i>,</b>
<b>int <i>stringcount</i>, const char *<i>stringname</i>,</b>
<b>char *<i>buffer</i>, int <i>buffersize</i>);</b>

DESCRIPTION
</b><br>
<P>
This is a convenience function for extracting a captured substring, identified
by name, into a given buffer. The arguments are:
<pre>
  <i>code</i>          Pattern that was successfully matched
  <i>subject</i>       Subject that has been successfully matched
  <i>ovector</i>       Offset vector that <b>pcre_exec()</b> used
  <i>stringcount</i>   Value returned by <b>pcre_exec()</b>
  <i>stringname</i>    Name of the required substring
  <i>buffer</i>        Buffer to receive the string
  <i>buffersize</i>    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.
