PCRE2 — Perl-compatible regular expressions (revised API)
#include <pcre2.h> pcre2_match_data *pcre2_match_data_create(uint32_tovecsize
, pcre2_general_context *gcontext
);
This function creates a new match data block, which is
used for holding the result of a match. The first argument
specifies the number of pairs of offsets that are required.
These form the "output vector" (ovector) within the match
data block, and are used to identify the matched string and
any captured substrings when matching with pcre2_match
(), or a number of different
matches at the same point when used with pcre2_dfa_match
(). There is always one pair
of offsets; if ovecsize
is
zero, it is treated as one.
The second argument points to a general context, for custom memory management, or is NULL for system memory management. The result of the function is NULL if the memory for the block could not be obtained.
There is a complete description of the PCRE2 native API in the pcre2api(3) page and a description of the POSIX API in the pcre2posix(3) page.
