Threads in Linux!

[Joda]

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!

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
