       mouse_getcaps - returns the capabilities of the mouse


       #include <vgamouse.h>

       int mouse_getcaps(struct MouseCaps *caps);


       This  fills  a structure with information about the capabilities of the
       mouse as configured in /etc/vga/libvga.config.

       The return value is 0 on success, -1 on failure. Failure indicates that
       an  older  version  of  the svgalib library is being used that does not
       support this function, and the capabilities should be inferred from the
       mouse type as retrieved by the function vga_getmousetype(3).

       The MouseCaps structure contains the following members:

       int key;
              After  a  successful call of mouse_getcaps this should be set to
              MOUSE_GOTCAPS.  The values of this and  the  other  members  are
              undefined in the case of failure.
       int buttons;
              A  bitmask indicating which buttons are supported by the device,
              composed of the constants MOUSE_LEFTBUTTON,  MOUSE_MIDDLEBUTTON,
              MOUSE_SIXTHBUTTON,    and    MOUSE_RESETBUTTON.    Note     that
              MOUSE_MIDDLEBUTTON  may  be  set when using mouse protocols that
              support a middle button even if there is  no  button  physically
              present on the mouse.
       int axes;
              A  bitmask  indicating  which  axes are supported by the device,
              composed of the constants  MOUSE_XDIM,  MOUSE_YDIM,  MOUSE_ZDIM,
       int info;
              A   bitmask   indicating  other  information  about  the  mouse.
              Currently the only  field  defined  is  MOUSE_INFO_WHEEL,  which
              indicates that the mouse is a wheel mouse.
       int reserved0;
              Reserved for future use.
       int reserved1;
              Reserved for future use.

       Your application may use this info to perform specific actions (go into
       a 3d pointer device mode or make use  of  a  wheel  for  scrolling  for
