I am beginner to C. I try to make a system call with
int system(const char *command)
and want to read back certain output strings from the screen. Which C function can do this?
For example, if I run:
ping 192.168.0.1 -c 2
I will get something like:
2 packets transmitted, 0 received
on the screen. If I can read back the string, I am able to analyze how many packets were received, etc.
So far I have thought about an awkward solution, ie. make the system call and save the output to a file:
ping 192.168.0.1 -c 2 > output.txt
Then I can use fopen() and fscanf() on output.txt.
Does anyone have any smarter ideas without saving a file? Thank you for help!
