NAME         top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS         top

       #include <pcre2.h>

       pcre2_match_data *pcre2_match_data_create_from_pattern(
         const pcre2_code *code, pcre2_general_context *gcontext);

DESCRIPTION         top

       This function creates a new match data block 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 when matching with
       pcre2_match(). If you are using pcre2_dfa_match(), which uses the
       output vector in a different way, you should use
       pcre2_match_data_create() instead of this function.

       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.
