[PRINTING]
Apply a consistent style to all similar functions:
- Spoolss functions don't necessarily set ERROR_SUCCESS. Check the boolean return value instead and only query the error code on failure.
- Use AlignRpcPtr and UndoAlignRpcPtr wherever feasible.
- Use one static function per level that can be called from both Get* and Enum* APIs.
- Use PackStrings in all functions that return structures with strings.
- Add TRACEs to all non-static functions in localspl.
- Pass a double pointer to all Marshalling functions and advance to the next structure there.
- Perform sanity checks and return the right error codes in a Windows-compatible way.
- Return TRUE when an Enum* API has no elements to enumerate.
