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.
