Hi,
I'm writing a daemon using libevent. The daemon is started like this:
"program_A | daemon"
It gets a pipe on standard input. The program_A is writing to this pipe and the
daemon must process the input gathered from the pipe. I must be doing something
wrong as my callback function set in event_set is called nonstop. A trace had
shown that epoll_wait() in epoll_dispatch() is not waiting at all and
afterwards the read() in the callback returns always 0. When I start the daemon
like this "./daemon" and write on the console, it all works fine as it should.
Here is my daemon skeleton:
struct event ev;
void read_stdin (int fd, short flags, void *data)
{
..
ret = read(fd, buf, BUFSIZE);
..
}
main ()
{
base = event_init();
event_set(&ev, 0, EV_READ | EV_PERSIST, read_stdin, NULL);
event_add(&ev, NULL);
event_base_loop(base, 0);
}
Thanks for any advice in advanced,
Tom
