| 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 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. |
| </P> |
| <P> |
| The second argument points to a general context, for custom memory management, |
| or is NULL to use the same memory allocator as was used for the compiled |
| pattern. The result of the function is NULL if the memory for the block could |
| not be obtained. |
