    Finding active computers in local network.

    Hi guys!
    How can I find out what computers in my local network? I need to implement something similar to this:

    nmap -sP
    But need to implement it using pure C code without calling system().

    nmap works pretty fast it doesn't look like it uses usual ping.

    Well between using wireshark and looking at the source code for nmap (isn't open source grand), I'm sure you should be able to figure something out.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
