X11R7.4 - man page for pcre_get_substring (x11r4 section 3)

PCRE_GET_SUBSTRING(3)		     Library Functions Manual		    PCRE_GET_SUBSTRING(3)

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 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
       invalid.

       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.
