I checked in the writer companion to %io-port-read-succession yesterday, %io-port-write-succession. These operators move untyped data (in units of 8, 16 or 32 bits) between memory and I/O ports. I've tried to introduce the % notation from the lisp-machines. It's my understanding that operator-names beginning with % signalled an unsafe operation, that if not used with care could damage the run-time invariants. The idea (on my part) is that such operators are the building blocks above which more useable operators are written, that take care of appropriate type-checking etc. before doing the dangerous operation. -- Frode Vatvedt Fjeld _______________________________________________ movitz-devel site list [email protected] http://common-lisp.net/mailman/listinfo/movitz-devel
