define COLLECTIONPOSITIONSIZE(p) (sizeof(DWORD) * ((p)->Level+2))

Parameters : Input : collpos - Pointer to a COLLECTIONPOSITION. Note : The Level and Tumbler array values for the COLLECTIONPOSITION must have been previously assigned.

Output : (routine) - Returns size of the COLLECTIONPOSITION structure in bytes.
