|
|
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>
|
|
|
|
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.
|
|
<P>
