SYNOPSIS         top


       #include <pcre2.h>

       pcre2_match_data *pcre2_match_data_create(uint32_t ovecsize,
         pcre2_general_context *gcontext);

DESCRIPTION         top


       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.
