Programming style...

originated in the java corner, i have some difficulties to adapt the
programming style used in the platform sdk and the ddk. therefore i'd like to
know what you think about the way i handled some things.

1) device interface GUIDs not defined in a global header:
i tried to find the GUID of disc type devices which are part of the mass
storage device group. because i didn't find any, i looked up the GUID value
stored in my registry and defined it in my app. is this a bad habit or can i
assume that this GUID never changes in further versions of ms win?

2) error checking:
SetupDiGetClassDevs and many other functions return a specific value if they
fail. so should i check for failure although such case is impossible? e.g.
SetupDiGetClassDevs with GUID_DEVINTERFACE_VOLUME should never fail. i ask
because useless failure checks make the code unreadable.
.
