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. There is always one pair of offsets; if <B>ovecsize</B> is zero, it
|
|
is treated as one.
|
|
<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.
|
|
