char *
XtCalloc(num,size)
>>ASSERTION Good A
A successful call to 
char *XtCalloc(num, size)
shall allocate space for 
.A num 
number of array elements each of size
.A size 
and initialize the space to zero.

>>ASSERTION Good A
When there is insufficient memory to allocate the requested
block a call to 
char *XtCalloc(num, size)
shall issue an allocError error and return NULL.

>>ASSERTION Good B 2
The order and contiguity of the storage allocated by 
successive calls to
char *XtCalloc(num, size).
>>ASSERTION Good B 1
A successful call to
char *XtCalloc(num, size)
shall return a pointer to an object that is disjoint from
any other object.
>>ASSERTION Good B 1
The pointer returned by a successful call to
char *XtCalloc(num, size)
shall point to the lowest byte address of the 
allocated space.
>>ASSERTION Good B 2
The pointer returned by a call to 
char *XtCalloc(num, size)
when 
.A size
is zero.
