NAME

       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int pcre_copy_substring(const char *subject, int *ovector,
            int stringcount, int stringnumber, char *buffer,
            int buffersize);

DESCRIPTION

       This is a convenience function for extracting a captured substring into
       a given buffer. The arguments are:

         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
         buffer        Buffer to receive the string
         buffersize    Size of buffer

       The yield is the legnth  of  the  string,  PCRE_ERROR_NOMEMORY  if  the
       buffer was too small, or PCRE_ERROR_NOSUBSTRING if the string number is
       invalid.

       There is a complete description of the PCRE native API in  the  pcreapi
       page and a description of the POSIX API in the pcreposix page.
