Reserves space in the array buffer.

If necessary, the array buffer is allocated or re-allocated so that it can accommodate the specified number of TUid elements.

After a successful call to this function, elements can be added to the array and the process is guaranteed not to fail for lack of memory - provided the total number of elements does not exceed the specified number.

This function does not increase the number of elements in the array; i.e. the member function CArrayFixBase::Count() returns the same value both before and after a call to this function.

panic

E32USER-CBase 27, if aCount is less than the current number of elements in the array.
