SYNOPSIS
 

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


int pcre_get_substring(const char *subject, int *ovector,
int stringcount, int stringnumber,
const char **stringptr);

 
DESCRIPTION
 

This is a convenience function for extracting a captured substring. The
arguments are:
<pre>
 subject Subject that has been successfully matched
 ovector Offset vector that pcre_exec() used
 stringcount Value returned by pcre_exec()
 stringnumber Number of the required substring
 stringptr Where to put the string pointer
</pre>
The memory in which the substring is placed is obtained by calling
pcre_malloc(). The convenience function pcre_free_substring() can
be used to free it when it is no longer needed. The yield of the function is
the length of the substring, PCRE_ERROR_NOMEMORY if sufficient memory could not
be obtained, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
