This is my code that sets bPolyAvailable to true if appropriate. However, on
the Tungsten 21 it comes up with true. I've changed the code based on Tom
Frauenhofer's suggestions. What am I missing? Do I need to do a device check
for the Zire21 and set it to false?
// globals
Boolean bPolyAvailable = false;
void Function(void)
{
UInt32 version;
Err err;
err = FtrGet(sysFileCSoundMgr, sndFtrIDVersion, &version);
// if(err != ftrErrNoSuchFeature) {
if(err == errNone) {
if(version == sndMgrVersionNum) {
bPolyAvailable = true;
}
}
// account for Palm Tungsten T not having the Streaming Sound feature
if(bPolyAvailable == false) {
if(SysGetTrapAddress(sysTrapSndStreamCreate) !=
SysGetTrapAddress(sysTrapSysUnimplemented)) {
bPolyAvailable = true;
}
}
if(bPolyAvailable == false)
return;
// do more stuff
}
Thanks,
Mike
