       pcre2_match_data *pcre2_match_data_create(uint32_t ovecsize,
         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 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 off-
       sets; if ovecsize is zero, it is treated as one.

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