UINT32 EFIAPI RRotU32 ( IN UINT32  Operand,
IN UINTN  Count 
)

Rotates a 32-bit integer right between 0 and 31 bits, filling the high bits with the low bits that were rotated.

This function rotates the 32-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 31, then ASSERT().

Parameters:
Operand The 32-bit operand to rotate right.
Count The number of bits to rotate right.
Returns:
Operand >> Count.

References ASSERT.
