NAME

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS


       #include <pcre2.h>

       pcre2_match_data *pcre2_match_data_create_from_pattern(
         const pcre2_code *code, 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  points  to  a  compiled  pattern.  The  number  of  capturing
       parentheses  within the pattern is used to compute the number of pairs of offsets that are
       required in the match data block. These form the  "output  vector"  (ovector)  within  the
       match data block, and are used to identify the matched string and any captured substrings.

       The  second argument points to a general context, for custom memory management, or is NULL
       to use the same memory allocator as was used for the compiled pattern. 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.
