how to send a message to the server
I wrote a my own server. it's quite simple, it takes a message filled
with a vector of ten integer and
perform their ordering.
The paradigm involved is the conventional event driven.
I also wrote a process called "client" which sends with the IPC
sendrec a message to it with the ten random integers
The only way to send a message from the client to my own server is to
run them by the mean of the service interface.
service up /myfoldef/myserver
servie up /myfolder/myclient
if I don't start the client up in this way, it's aborted. I think it's
killed by the kernel.
Unfortunately by starting both processes (myclient and myserver) as
showed, they become "server" in the minix layer on the contrary I want
only myserver to be a server belonging to Minix' server layer and the
client to be a common user process able to send messages to my server.
How can I fix this ?
Thank you in advance.

IIRC, normal user processes are not allowed to call sendrec directly, but
have to use the _syscall function(). This also requires of you to make a
new system call entry in the system call table so that your _syscall()
resolves to something meaningful. However, I don't have any source code at
hand (and the SVN repository browser is down, again), so I can't tell you
exactly where or how to do this, but look it up.
