How to capture ping's return value in C++

Question

Does anyone know, how to capture ping's return value in c++? According to this link: ping should return 0 on success, 1 on failure such as unknown host, illegal packet size, etc. and 2 On a unreachable host or network.

In C++ I called ping with the system (), e.g. int ret = system("ping 192.168.1.5");.

My problem is, that ret's value is 0 or 1. It will never 2! If I think correctly, this is because, this return value I get, is the system functions return value, not ping's. So how could i get ping's return vlaue?

Thanks in advance!

Edit: Right now i use this system("ping 192.169.1.5 > ping_res.txt"); but i don't want to work with files (open, and read them), that's why i want to capture, th return value , if possible :)

Answer 1

If you are on Windows, it might be better to use IcmpSendEcho2 directly to implement the ping functionality in your application.

Answer 2

A simple solution would be pipe the output of ping to to a file and read it.

E.g.

system("ping 192.169.1.5 > ping_res.txt");

And read ping_res.txt to get the info you need.
