rtf handler problems

[Olaf Petzold]

Hello,

what's wrong with the following code. If I do a read op on user space the
handler isn't called. If I read the man page right, the installed handler is
called on all ops regardless read/write.

 # uname -a
Linux rtreg 2.2.17-rtl3b9 #2 Thu Dec 7 10:25:11 CET 2000 i686 unknown                  
                                   

Thanks,
Olaf
