Re: get stdout/stderr while running a program

[kgold]

emacs uses a pipe to route stdout to the buffer.  The C default for
pipes is fully buffered.  So you don't see the output until exit or
the buffer is full.

Put this into your C program main():

    setvbuf(stdout,0,_IONBF,0);

I'm not sure about stderr, since I thought it was unbuffered by
default..
