The name is available directly from the GetComponentInfo function but
it's still
kind of buried.
Here's the code I adapted from the SoundConverter example code to get
the name
out of a Component. There's probably a simpler way :-). I still don't
know how to get the
info text.
Handle name = NewHandle(0);
char cname[256];
while (theAUComponent != NULL){
ComponentDescription theDesc;
GetComponentInfo(theAUComponent, &theDesc, name, nil, nil);
if (theDesc.componentManufacturer !=
kAudioUnitManufacturer_Apple) {
HLock( name );
char* length = *name;
strncpy(cname, (char*)((*name)+1), length[0]);
cname[length[0]] = 0;
HUnlock( name );
}
theAUComponent = FindNextComponent (theAUComponent, &desc);
}
DisposeHandle( name );
