Fixed bug #853 Ludwig Nussel 2009-10-18 05:34:18 PDT src/joystick/linux/SDL_sysjoystick.c has some problems: - test_bit() might break with strict aliasing - test_bit() assumes array is Uint32 but its actually "unsigned long" on 64bit systems sizeof(long) != sizeof(Uint32). - the keybit array is too small - the arrays are unitialized so the number of detected buttons is quite random

11 The current button state is returned as a button bitmask, which can be tested using the \fBSDL_BUTTON(X)\fP macros, and \fBx\fR and \fBy\fR are set to the change in the mouse position since the last call to \fBSDL_GetRelativeMouseState\fP or since event initialization\&. You can pass \fBNULL\fP for either \fBx\fR or \fBy\fR\&.
