question about mouse_event

[dd jj]

Hello,
 
I have ported a windows code to linux using winemaker: it works fine on windows, but doesn't work on linux, Could anyone give some comments on this problem? THanks.
 
Here's the code.
 
#include <windows.h>
int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
  // TODO: Place code here.
    mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
    mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
 return 0;
}
