Root include file for Mde Package Base type modules
|
|
|
|
This is the include file for any module of type base. Base modules only use
|
|
types defined via this include file and can be ported easily to any
|
|
environment. There are a set of base libraries in the Mde Package that can
|
|
be used to implement base modules.

// For modules that use the ISO C library interfaces for variable

|
|
//
|
|
// VA_LIST - typedef for argument list.
|
|
// VA_START (VA_LIST Marker, argument before the ...) - Init Marker for use.
|
|
// VA_END (VA_LIST Marker) - Clear Marker
|
|
// VA_ARG (VA_LIST Marker, var arg type) - Use Marker to get an argument from
|
|
// the ... list. You must know the type and pass it in this macro. Type
|
|
// must be compatible with the type of the actual next argument (as promoted
|
|
// according to the default argument promotions.)
|
|
// VA_COPY (VA_LIST Dest, VA_LIST Start) - Initialize Dest as a copy of Start.

//
|

// UINTN
|

// EFIAPI
|
|
// ExampleVarArg (

// - Functions that call VA_START() / VA_END() must have a variable

// - Functions that call VA_COPY() / VA_END() must be declared EFIAPI.
|
