GetNumberOfConsoleMouseButtons

The GetNumberOfConsoleMouseButtons function retrieves the number of buttons on the mouse used by the current console.

BOOL GetNumberOfConsoleMouseButtons(
  LPDWORD lpNumberOfMouseButtons   // number of buttons
);

Parameters

lpNumberOfMouseButtons

[in] Pointer to a variable that receives the number of mouse buttons.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

When a console receives mouse input, an INPUT_RECORD structure containing a MOUSE_EVENT_RECORD structure is placed in the console's input buffer. The dwButtonState member of MOUSE_EVENT_RECORD has a bit indicating the state of each mouse button. The bit is 1 if the button is down and 0 if the button is up. To determine the number of bits that are significant, use GetNumberOfConsoleMouseButtons.
