printing-a (below)... :-)
HRESULT
IsPowerOf2(
IN UINT uPow2
)
{
//
// Check if uPow2 is really a power of 2, there are faster
// ways of doing this, but for now lets just get it done.
//
UINT uNumOfSetBits = 0;
for (UINT i = 1; i; i = i << 1)
{
uNumOfSetBits += (uPow2 & i) ? 1
: 0;
}
return uNumOfSetBits == 1 ? S_OK : S_FALSE;
}
