617c478bd9Sstevel@tonic-gate  * 		char * _Malloc (int item_count, int item_size);
627c478bd9Sstevel@tonic-gate  * 	which does NOT (necessarily) initialize the allocated storage,
637c478bd9Sstevel@tonic-gate  * 	and which issues an error message and calls exit() if
647c478bd9Sstevel@tonic-gate  * 	the storage could not be allocated.
