Dear o.u.c_cpp,

OpenWatcom has several different interrupt routines, namely

   int386
   int386x
   int86
   int86x
   intdos
   intdosx
   intr
   intrf

and others.  The C Library Reference doesn't include any hint on when I 
should choose one function over another.

So far I've just used intr() because it's the first one I came across. 
Is it any better to use int386() or int386x() in protected mode 
applications?

If context matters, then for now I'm mostly interested in the int 33 
mouse functions.

[Copied but not cross posted to the c.o.m.programmer newsgroup, because 
I'm using different NNTP servers.]
