Define Documentation

#define ASM_GLOBAL   .globl

For GNU assembly code, .global or .globl can declare global symbols. Define this macro to unify the usage.

#define CPU_STACK_ALIGNMENT   16

The stack alignment required for x64

#define EFIAPI   __cdecl

Microsoft* compiler specific method for EFIAPI calling convention.

#define FUNCTION_ENTRY_POINT ( FunctionPointer   )     (VOID *)(UINTN)(FunctionPointer)

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.

#define MAX_2_BITS   0xC000000000000000ULL

A value of native width with the two highest bits set.

#define MAX_ADDRESS   0xFFFFFFFFFFFFFFFFULL

Maximum legal x64 address

#define MAX_BIT   0x8000000000000000ULL

A value of native width with the highest bit set.

#define MAX_INTN   ((INTN)0x7FFFFFFFFFFFFFFFULL)

Maximum legal x64 INTN and UINTN values.

#define MAX_UINTN   ((UINTN)0xFFFFFFFFFFFFFFFFULL)

#define MDE_CPU_X64

Define the processor type so other code can make processor based choices


Typedef Documentation

typedef unsigned char BOOLEAN

Logical Boolean. 1-byte value containing 0 for FALSE or a 1 for TRUE. Other values are undefined.

typedef unsigned short CHAR16

2-byte Character. Unless otherwise specified all strings are stored in the UTF-16 encoding format as defined by Unicode 2.1 and ISO/IEC 10646 standards.

typedef char CHAR8

1-byte Character

typedef short INT16

2-byte signed value

typedef __int32 INT32

4-byte signed value

typedef __int64 INT64

8-byte signed value

typedef signed char INT8

1-byte signed value

typedef INT64 INTN

Signed value of native width. (4 bytes on supported 32-bit processor instructions, 8 bytes on supported 64-bit processor instructions)

typedef unsigned short UINT16

2-byte unsigned value

typedef unsigned __int32 UINT32

4-byte unsigned value

typedef unsigned __int64 UINT64

8-byte unsigned value

typedef unsigned char UINT8

1-byte unsigned value

typedef UINT64 UINTN

Unsigned value of native width. (4 bytes on supported 32-bit processor instructions, 8 bytes on supported 64-bit processor instructions)
