PCRE_GET_SUBSTRING_LIST

Section: C Library Functions (3)
Updated: 24 June 2012
Index Return to Main Contents
 

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 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.
