		IN UINTN	Count
	)

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

This function rotates the 64-bit value Operand to the left by Count bits. The low Count bits are fill with the high 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 left.
