PCRE2_MATCH_DATA_CREATE(3) Introduction to Library Functions

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.
