The UInt32x32To64 function multiplies two unsigned 32-bit integers, returning an unsigned 64-bit integer result. The function performs optimally on all Win32 platforms.

DWORDLONG UInt32x32To64(

DWORD Multiplier,	// specifies first unsigned 32-bit integer for the multiplication
DWORD Multiplicand	// specifies second unsigned 32-bit integer for the multiplication
);

Parameters
Multiplier

Specifies the first unsigned 32-bit integer for the multiplication.

Multiplicand

Specifies the second unsigned 32-bit integer for the multiplication.

Return Values
The return value is the unsigned 64-bit integer result of the multiplication.

Remarks
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.
