Thread: Capture system call output?

I want to be able to call something like "wc -l file.c" and pipe that information back into the program I'm running. I've googled and found some information on popen, but that doesn't seem to help any. I've tried to consider some redirecting or piping but to no avail. Any ideas?

Thanks in advance

Honestly, I didn't "try" it. I was looking at the man page:

FILE *popen(const char *command, const char *type);

.........

Ok this is the point where I smile like an idiot and walk away. I went with your advice and tried it. Worked perfectly.

Thanks again
