       PCRE - Perl-compatible regular expressions


       #include <pcre.h>

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


       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 con-
       venience 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

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