Function Documentation

ARShiftU64()

UINT64 EFIAPI ARShiftU64	(	IN UINT64	Operand,
		IN UINTN	Count
	)

Shifts a 64-bit integer right between 0 and 63 bits. The high bits are filled with the original integer's bit 63. The shifted value is returned.

This function shifts the 64-bit value Operand to the right by Count bits. The high Count bits are set to bit 63 of Operand. The shifted value is returned.

If Count is greater than 63, then ASSERT().

Parameters

Operand	The 64-bit operand to shift right.
Count	The number of bits to shift right.

Returns

Operand >> Count
