Multiplies two signed 32-bit integers, returning a signed 64-bit integer result. The function performs optimally on 32-bit Windows.
void Int32x32To64( a, b );
The first signed 32-bit integer for the multiplication operation.
The second signed 32-bit integer for the multiplication operation.
This function is implemented on all platforms by optimal inline code: a single multiply instruction that returns a 64-bit result.
Please note that the function's return value is a 64-bit value, not a LARGE_INTEGER structure.
