21 This is a convenience function for extracting a list of all the captured
22 substrings. The arguments are:
23 .sp
24 \fIsubject\fP Subject that has been successfully matched
25 \fIovector\fP Offset vector that \fBpcre[16]_exec\fP used
26 \fIstringcount\fP Value returned by \fBpcre[16]_exec\fP
27 \fIlistptr\fP Where to put a pointer to the list
28 .sp
29 The memory in which the substrings and the list are placed is obtained by
30 calling \fBpcre[16]_malloc()\fP. The convenience function
31 \fBpcre[16]_free_substring_list()\fP can be used to free it when it is no
32 longer needed. A pointer to a list of pointers is put in the variable whose
33 address is in \fIlistptr\fP. The list is terminated by a NULL pointer. The
34 yield of the function is zero on success or PCRE_ERROR_NOMEMORY if sufficient
35 memory could not be obtained.
