Stream stdout to file

Hi,

I want my program to launch another program and read std out from it..this isn't a problem. However this other program never returns it just keeps on spewing out data. I'm wanting to capture this data and stream it to a file as it's received. Is this possible? I can't do this in a loop in my program because it needs to do other processing in parallel to this task.

Any help much appreciated.

So are you just going to keep asking, or are you going to post an attempt using popen() or some mix of fork/exec/dup calls to allow two processes to communicate?

Don't feel like writing a response, so you get year+ old threads. See my code example here. YMMV.
