PCRE_GET_SUBSTRING_LIST(3)				     Library Functions Manual					PCRE_GET_SUBSTRING_LIST(3)

NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int pcre_get_substring_list(const char *subject,
	    int *ovector, int stringcount, const char ***listptr);

DESCRIPTION

       This is a convenience function for extracting a list of all the captured substrings. The arguments are:

	 subject       Subject that has been successfully matched
	 ovector       Offset vector that pcre_exec used
	 stringcount   Value returned by pcre_exec
	 listptr       Where to put a pointer to the list

       The  memory  in	which the substrings and the list are placed is obtained by calling pcre_malloc(). The convenience function pcre_free_sub-
       string_list() can be used to free it when it is no longer needed. A pointer to a list of pointers is put in the variable whose  address	is
       in  listptr.  The  list	is terminated by a NULL pointer. The yield of the function is zero on success or PCRE_ERROR_NOMEMORY if sufficient
       memory could not be obtained.

       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.
