Hi Douglas, Scott et al, I have once heard of a way to get a OS5 patch trapped. Did anyone of you ever look at YAHM? Best regards Tam Hanna

However, if your goal is to intercept and pre-examine all BT, IR and network traffic, operating from an alarm is probably not going to be a satisfactory arrangement. For that matter, the same may be true of a sound stream callback or event dequeue notifications. Prior to OS5, you would do some something like this by using SysSetTrapAddress() to preempt various APIs, much the way TSR programs operated in the days of DOS. A "hack" manager made this process safer when multiple apps tried to usurp the same APIs. However, in OS5 the ability to use SysSetTrapAddress() is no longer implemented. I'd suggest before you figure out how to make a background process run, you first think about how you'll intercept all the comm traffic and then only think about how you can have that code active to act as a filter on incoming comms.
