Definition at line 295 of file ProcessorBind.h.

◆ FUNCTION_ENTRY_POINT

#define FUNCTION_ENTRY_POINT ( FunctionPointer )

Value:

(VOID *)(UINTN)(FunctionPointer)

UINTN

UINT64 UINTN

Unsigned value of native width.

Definition ProcessorBind.h:115

VOID

#define VOID

Undeclared type.

Definition Base.h:272

Return the pointer to the first instruction of a function given a function pointer.

On x64 CPU architectures, these two pointer values are the same, so the implementation of this macro is very simple.

Parameters

FunctionPointer A pointer to a function.

Returns: The pointer to the first instruction of a function given a function pointer.
