The Int32x32To64 function multiplies two signed 32-bit integers, returning a signed 64-bit integer result. The function performs optimally on all Win32 platforms.
LONGLONG Int32x32To64(
|
LONG Multiplier, |
// specifies first signed 32-bit integer for the multiplication |
|
LONG Multiplicand |
// specifies second signed 32-bit integer for the multiplication |
|
); |
The return value is the signed 64-bit integer result of the multiplication.
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.
