This can't possibly be code that you have compiled.
1. prefs is a typedef; no space has been allocated for a variable.
2. the 5th parameter to PrefSetAppPreferences should be a UInt16, not a
pointer to whatever you declared prefsize to be.
What kind of compiler doesn't catch these errors?

Well, since &prefsize is interpreted as a UInt16, it's not too
surprising that it doesn't contain the correct value.
