Use -ARES_SOCKET_BAD for "no action". This function is provided to allow users of -c-ares to avoid \fIselect(3)\fP in their applications and within c-ares. - -To only process possible timeout conditions without a socket event occurring, -one may pass NULL as the values for both \fIread_fds\fP and \fIwrite_fds\fP for -\fBares_process(3)\fP, or ARES_SOCKET_BAD for both \fIread_fd\fP and -\fIwrite_fd\fP for \fBares_process_fd(3)\fP. -.SH EXAMPLE -The following code fragment waits for all pending queries on a channel -to complete: - -.nf -int nfds, count; -fd_set readers, writers; -struct timeval tv, *tvp; - -while (1) { - FD_ZERO(&readers); - FD_ZERO(&writers); - nfds = ares_fds(channel, &readers, &writers); - if (nfds == 0) - break; - tvp = ares_timeout(channel, NULL, &tv); - count = select(nfds, &readers, &writers, NULL, tvp); - ares_process(channel, &readers, &writers); -} -.fi -.SH SEE ALSO -.BR ares_fds (3), -.BR ares_timeout (3) -.SH AUTHOR -Greg Hudson, MIT Information Systems -.br -Copyright 1998 by the Massachusetts Institute of Technology. |
