I have two processes(A, C) and one thread(B). C wants to print information to streams such as STDERR or STDOUT and A wants to have control over what information that is sent here by reading from these streams constantly. (Important that there are two streams ant not just one)

Basically This is the following pseudo:

A: Fork a new thread B

B: Execute an external process C

B: wait for C to finish, then exit

A: While(STDERR | STDOUT) from C

A: print information.

I've been trying with pipes and shared variables but been unable to make it work. Does anyone have code or perhaps simple code to illustrate this?
