MOUSE_DRIVER is a struct.

[julmuri]

It is a type of structure that defines four types of public variables

   int  id;
   AL_CONST char *name;
   AL_CONST char *desc;
   AL_CONST char *ascii_name

I suppose that AL_CONST is equivalent of const, ie

#define AL_CONST const

And rest are member functions:

   AL_METHOD(int,  init, (void));
   AL_METHOD(void, exit, (void));
   AL_METHOD(void, poll, (void));
   AL_METHOD(void, timer_poll, (void));
   AL_METHOD(void, position, (int x, int y));
   AL_METHOD(void, set_range, (int x1, int y_1, int x2, int y2));
   AL_METHOD(void, set_speed, (int xspeed, int yspeed));
   AL_METHOD(void, get_mickeys, (int *mickeyx, int *mickeyy));
   AL_METHOD(int,  analyse_data, (AL_CONST char *buffer, int size));
   AL_METHOD(void, enable_hardware_cursor, (int mode));
   AL_METHOD(int,  select_system_cursor, (int cursor));

AL_METHOD being

#define AL_METHOD( ret, name, ... ) ret name( ... ) 

or some such, macro horror.
You can look up the definitions.
