|
PCRE2 - Perl-compatible regular expressions (revised API)

.SH SYNOPSIS

.rs

.SH DESCRIPTION
|
|
.rs
|
|
.sp
|
|
This is a convenience function for extracting all the captured substrings after
|
|
a pattern match. It builds a list of pointers to the strings, and (optionally)
|
|
a second list that contains their lengths (in code units), excluding a
|
|
terminating zero that is added to each of them. All this is done in a single
|
|
block of memory that is obtained using the same memory allocation function that
|
|
was used to get the match data block. The convenience function
|
|
\fBpcre2_substring_list_free()\fP can be used to free it when it is no longer
|
|
needed. The arguments are:
|
|
.sp
|
|
\fImatch_data\fP The match data block
|
|
\fIlistptr\fP Where to put a pointer to the list
|
|
\fIlengthsptr\fP Where to put a pointer to the lengths, or NULL
|
|
.sp
|
|
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. If \fIlengthsptr\fP is
|
|
not NULL, a matching list of lengths is created, and its address is placed in
|
|
\fIlengthsptr\fP. The yield of the function is zero on success or
|
|
PCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained.
