Section (3) pcre2_match_data_create
PCRE2 — Perl-compatible regular expressions (revised API)
#include <pcre2.h> pcre2_match_data *pcre2_match_data_create(uint32_t
ovecsize, pcre2_general_context *
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. There is always one pair of offsets;
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.
