NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
pcre2_match_data *pcre2_match_data_create(uint32_t ovecsize,
pcre2_general_context *gcontext);
DESCRIPTION
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 page and a description of the POSIX API in the
pcre2posix page.
