IME Exported Entries
Here are the specification of IME exported entries which IME must provide. These entries are only callable from the system, i.e., not directly callable from the application. Because IME is callable from non-PM environment, such as FS or DOS, IME should not issue any of the PM related calls which require the PM message queue. IME must export all of the API entries listed below. There are functions which are not mandatory to support. Those functions can be distinguished by the return code. If the error code ERROR_NOT_SUPPORTED is available in some function, it means that the function is not mandatory.
