NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       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:

	 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

       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 mem-
       ory could not be obtained, 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.
