 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
-<b>pcre2_match()</b>. If you are using <b>pcre2_dfa_match()</b>, which uses the
-output vector in a different way, you should use <b>pcre2_match_data_create()</b>
-instead of this function.
