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.
