Function Documentation

INTN EFIAPI LowBitSet64 ( IN UINT64  Operand)

Returns the bit position of the lowest bit set in a 64-bit value.

This function computes the bit position of the lowest bit set in the 64-bit value specified by Operand. If Operand is zero, then -1 is returned. Otherwise, a value between 0 and 63 is returned.

Parameters:
OperandThe 64-bit operand to evaluate.
Return values:
0..63The lowest bit set in Operand was found.
-1Operand is zero.
