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);

       int pcre16_get_substring_list(PCRE_SPTR16 subject,
	    int *ovector, int stringcount, PCRE_SPTR16 **listptr);

       int pcre32_get_substring_list(PCRE_SPTR32 subject,
	    int *ovector, int stringcount, PCRE_SPTR32 **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[16|32]_exec used
	 stringcount   Value returned by pcre[16|32]_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[16|32]_malloc(). The convenience function
       pcre[16|32]_free_substring_list() can be used to free it when it is no longer needed. A pointer to a list of pointers is put in	the  vari-
       able  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.
