10 .B int pcre2_substring_list_get(pcre2_match_data *\fImatch_data\fP,
11 .B " PCRE2_UCHAR ***\fIlistptr\fP, PCRE2_SIZE **\fIlengthsptr\fP);
17 This is a convenience function for extracting all the captured substrings after
18 a pattern match. It builds a list of pointers to the strings, and (optionally)
19 a second list that contains their lengths (in code units), excluding a
20 terminating zero that is added to each of them. All this is done in a single
21 block of memory that is obtained using the same memory allocation function that
22 was used to get the match data block. The convenience function
23 \fBpcre2_substring_list_free()\fP can be used to free it when it is no longer
24 needed. The arguments are:
26 \fImatch_data\fP The match data block
27 \fIlistptr\fP Where to put a pointer to the list
28 \fIlengthsptr\fP Where to put a pointer to the lengths, or NULL
30 A pointer to a list of pointers is put in the variable whose address is in
31 \fIlistptr\fP. The list is terminated by a NULL pointer. If \fIlengthsptr\fP is
32 not NULL, a matching list of lengths is created, and its address is placed in
33 \fIlengthsptr\fP. The yield of the function is zero on success or
34 PCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained.
