I'm trying to do something REALLY simple here, but it just doesn't
work. All I wanna do is allocate a little memory, and then start up
the sound tools. Can someone tell me why this little bit of code
doesn't work?
/* global vars */
Word MyID;
Handle STHandle;
void startup()
{
int err=0;
MyID = MMStartUp();
STHandle = NewHandle((LongWord)0x100, MyID, 0xC005, NULL);
SoundStartUp(*STHandle);
}
From what I can tell, it's allocating the handle just fine, but when
it de-references it to a pointer, and sends it to SoundStartUp, it
crashes big time. Am I doing something fundamentally wrong here?

Change the call to the following and you should be okay: SoundStartUp((word)*STHandle); This is Apple and Bytework's fault for neither one providing prototyped tool headers- with prototyped headers, the compiler would have flagged an error at this construct. There was some talk on GEnie or AOL about prototyped headers having been created- I'll check that out. -- Jawaid Bazyar | "I'm sure K&R have never heard of Mike."
