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 oovveeccssiizzee 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 ppccrree22aappii page and a description of the POSIX API in the ppccrree22ppoossiixx page.
