Hi Hackers!
I am not a professional programmer as you are or I know much about
debug skills. But here I have a large multiprogramming program that I need
to hack into. The program can be divided into several functional modules
and a "kernel" module which handles all messages needed for every functinal
module. When one functinal module need to communicate with other modules,
it first send messages(with or without format) to "kernel" and then
"kerenl" will handle the message, deliver it to its destination. The
"kernel" also maintain a message queue for simultaneously coming messages.
The "kernel" is built up on a real time scheduled multi-tasking OS with
system calls support. It is trasparent to the functional modules.
Now the problem is, I need to test all functional modules to see if
they can process messages deserved to them correctly. What can I do? I
can't trace the activities of them because they only be executed when the
message comes and "kernel" call them. This mechanism is very different as
of the IPC operation on UNIX. Can you give some advice? I am sorry this may
not the right place for ask my question but I don't know better ones.
Thanks for reading this.
