Function Documentation

UINT64 EFIAPI RShiftU64 ( IN UINT64  Operand,
IN UINTN  Count 
)

Shifts a 64-bit integer right between 0 and 63 bits. This high bits are filled with zeros. 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 zero. 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.
