I haven't tried this, but seems like it should work:


#define MAXBACK 1

int numconn;


server()
{
    int oldmask;

    numconn = 0;
    /*create and bind socket */

    signal(SIGCHLD,decnumconn);
    for(;;) {
       if (numconn < MAXCONN) {
            err = listen(s,MAXBACK);

            oldmask = signal(SIGCHLD);
            sigblock(SIGCHLD);
            numconn++;
            sigsetmask(oldmask);

            /* accept,fork, etc. */
       }
    }
}

decnumconn()
{
    numconn--;
}



client()
{
    /*create and bind socket */

    while ((connect(..,..,..) < 0) {
         if (errno != ECONNREFUSED) return(-1);  /* or whatever */
    }

    /* transfer data */
}
