.SH DESCRIPTION
|
|
.rs
|
|
.sp
|
|
This is a convenience function for extracting a list of all the captured
|
|
substrings. The arguments are:
|
|
.sp
|
|
\fIsubject\fP Subject that has been successfully matched
|
|
\fIovector\fP Offset vector that \fBpcre[16|32]_exec\fP used
|
|
\fIstringcount\fP Value returned by \fBpcre[16|32]_exec\fP
|
|
\fIlistptr\fP Where to put a pointer to the list
|
|
.sp
|
|
The memory in which the substrings and the list are placed is obtained by
|
|
calling \fBpcre[16|32]_malloc()\fP. The convenience function
|
|
\fBpcre[16|32]_free_substring_list()\fP 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 \fIlistptr\fP. 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.
