    SubjectProblem with select?
    Hello,

    When I run the following program, and block the terminal's output
    (C-s), the `select' doesn't seem to have any effect, resulting in a
    100% cpu usage (this is on a RH8, with 2.4.18). I wouldn't be
    surprised if I'm doing something stupid, but it does seem to work fine
    on Solaris.

    Is there anything wrong with this, or is this some bug?

    ======================================================================
    #include <unistd.h>
    #include <fcntl.h>
    int main() {
    int flags, fd, len; fd_set writefds;
    fd = 1;
    flags = fcntl(fd, F_GETFL, 0);
    fcntl(fd, F_SETFL, flags | O_NONBLOCK);
    while (1) {
    FD_ZERO(&writefds);
    FD_SET(fd, &writefds);
    len = select(fd + 1, NULL, &writefds, NULL, NULL);
    if (!FD_ISSET(fd,&writefds)) exit(0);
    len = write(fd, "hi\n", 3);
    }
    fcntl(fd, F_SETFL, flags);
    }
    ======================================================================
