PCRE2 - Perl-compatible regular expressions (revised API)


       #include <pcre2.h>

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


       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 com-
       pute 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

       The second argument points to a general context, for custom memory man-
       agement, 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.
