| DESCRIPTION |
| </b><br> |
| <P> |
| 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 <b>pcre2_match()</b>, or a number of different |
| matches at the same point when used with <b>pcre2_dfa_match()</b>. There is |
| always one pair of offsets; if <b>ovecsize</b> is zero, it is treated as one. |
| </P> |
| <P> |
| 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. |
