    Exclamation Threads in Linux!

    hey!

    Im working on a imgviewer on linux, when I launch
    it from xterm it is using xterms's thread to
    recieve I/O. This is a problem, I want to
    use a separate thread and have it act as if
    I called the app using the & sign, like
    "./imgview &".

    How do I do this? I know some stuff about
    multithreaded apps but I dont think this is
    exactly what I want.

    All feedback is welcome!

    Code:
    int main(int argc, char *argv[])
    {
        pid_t pid;
        
        switch (pid = fork())
        {      
            case -1:    
                perror("fork");
                return (EXIT_FAILURE);
                break;
            case 0:
                sleep(1);
                if( setsid() == -1 )
                {
                    perror("setsid");
                }
                break;
            default:
                _exit(EXIT_SUCCESS);
                break;
        }
    
        /*
         * We have now forked and setup our own group, detached from the terminal
         */
    It's close to being complete.... I just hacked this out of an app, you can amend it to suit your needs
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
