-Module Name:
- CpuIo.h
-
-Abstract:
- *.h file for the driver
-
- Note: the EFIAPI on the CpuIo functions is used to glue MASM (assembler) code
- into C code. By making the MASM functions EFIAPI it ensures that a standard
- C calling convention is assumed by the compiler, reguardless of the compiler
- flags.
