DESCRIPTION

 |

<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. 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.
