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 length of the string, PCRE_ERROR_NOMEMORY if the  buf‐
       fer  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.
