Need help in kernel hacking

[Ronan-Yann Lorin]

I try to add a new syscall to the kernel.  I have been able to add an
entry in the os/init_sysent.c file.  My procedure is getting called.  But
I have two more problems:

1) I'm not able to transmit any parameters or function results
2) I don't know what is the meanning of the integer in each entry of
   the struct sysent in file os/init_sysent.c

Has someone done this successfully?

Thanks in advance.
