UINT64 EFIAPI RRotU64	(	IN UINT64	Operand,
		IN UINTN	Count
	)

Rotates a 64-bit integer right between 0 and 63 bits, filling the high bits with the high low bits that were rotated.

This function rotates the 64-bit value Operand to the right by Count bits. The high Count bits are fill with the low Count bits of Operand. The rotated value is returned.

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

Parameters

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