Ok, here is what I have presently, I've tried variations. I get an error
when re-entering the program about trying to write directly to null. The big
NULL parameter is the obvious suspect, but the Palm Developer Reference says
to do this to get the size of the buffer. Any help is appreciated.
void RetrieveDynamicStructure() {
if (PrefGetAppPreferences(APP_TYPE, dynamicPrefsID, NULL, &PrefSize,
true))
DynamicStructure = MemHandleNew(PrefSize);
dynamicStructure = MemHandleLock(DynamicStructure);
PrefGetAppPreferences(APP_TYPE, dynamicPrefsID, dynamicStructure,
&PrefSize, true);
}
}
void SaveDynamicStructure() {
if (dynamicStructure) PrefSetAppPreferences(APP_TYPE, dynamicPrefsID, 0,
dynamicStructure,
MemHandleSize(DynamicStructure),
true)
else PrefSetAppPreferences(APP_TYPE, dynamicPrefsID, 0, NULL, 0, true);
}
