PCRE - Perl-compatible regular expressions
Contents
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]_execlistptr 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.
