How to GET current primary mouse button settings using Win32 c#

Question

For setting the primary button I am using the SystemParametersInfoA method.

const int SPI_SETMOUSEBUTTONSWAP = 33;
SystemParametersInfo(SPI_SETMOUSEBUTTONSWAP, button, String.Empty, SPIF_UPDATEINIFILE | SPIF_SENDCHANGE);

But for getting the current mouse button I am not able to find any functions in SystemParametersInfoA.
Is there any function to get the mouse button using Win32 or any other?

Answer 1

According to the documentation for SystemParametersInfo - "To retrieve the current setting, call GetSystemMetrics with the SM_SWAPBUTTON flag". GetSystemMetrics function

SM_SWAPBUTTON
23 Nonzero if the meanings of the left and right mouse buttons are swapped; otherwise, 0.
