    In unix you might try getpid().

    www.rt.com/man
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    getpid() gives you the PID of the current process and not of any other process.

    It depends on what flavor of UNIX you are using. In Digital, you have a pseudo mount point called /proc/, in which each file is named after a process' PID. You can read a lot of information of a process just using read() on each of these files in here. But again, reading these files depends upon who the user is [permissions]. The best bet for you would be using the command 'ps'.
