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.  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.
