Code of IPC between driver servers and user processes

[maillis...@gmail.com]

Hi all,

I am new to Minix3.

I am interested in the IPC code in Minix3, which deals with the
communication of driver servers and user processes. But I don't find
the implementation but two "ipc.h" files in the code base from
"minix3.org".

So is there anyone know where the "*.c" files on IPC are?

Thanks in advance,
Dafu

Not sure what you're looking after.
Do you mean by "receive" and "send" implementations?
If yes, it's not implemented by *.c files, instead, it's written by assembly,
you can find it in ./lib/i86/rts/_sendrec.s.

In fact the real implementation is written in C.
The assembly lib files just make the kernel trap.
You can find the implementation of IPC in /usr/src/kernel/proc.c
(mini_send, mini_receive, mini_notify etc.).
