17 This function creates a new match data block, which is used for holding
18 the result of a match. The first argument specifies the number of pairs
19 of offsets that are required. These form the "output vector" (ovector)
20 within the match data block, and are used to identify the matched
21 string and any captured substrings when matching with pcre2_match(), or
22 a number of different matches at the same point when used with
23 pcre2_dfa_match(). There is always one pair of offsets; if ovecsize is
24 zero, it is treated as one.
25
26 The second argument points to a general context, for custom memory man‐
27 agement, or is NULL for system memory management. The result of the
28 function is NULL if the memory for the block could not be obtained.

30 There is a complete description of the PCRE2 native API in the pcre2api
31 page and a description of the POSIX API in the pcre2posix page.
