handler(int sig)
{
printf("Signal %d received\n", sig);
}
main()
{
int i, fd;
signal(SIGIO, handler);
fd = open("/dev/cuaa1", O_RDONLY | O_NONBLOCK | O_EXCL);
printf("%d\n", fd);
i = fcntl(fd, F_GETFL, 0);
printf("%d\n", i);
printf("%d\n", fcntl(fd, F_SETFL, i | O_ASYNC));
printf("%d\n", fcntl(fd, F_SETOWN, getpid())); /* This call returns -1 */
pause();
}
I've read the man page for fcntl() and it really appears as though
that F_SETOWN call should work. Any clues as to why not? This
is a snippet from some code that Thomas Roell sent me, wondering
why this didn't work under *BSD when it did under Linux.
