The parameter \fImaxtv\fP specifies a existing maximum timeout, or \fBNULL\fP if the caller does not wish to apply a maximum timeout. The parameter \fItv\fP must point to a writable buffer of type \fBstruct timeval\fP It is valid for \fImaxtv\fP and \fItv\fP to have the same value. If no queries have timeouts pending sooner than the given maximum timeout, \fBares_timeout(3)\fP returns the value of \fImaxtv\fP; otherwise \fBares_timeout(3)\fP stores the appropriate timeout value into the buffer pointed to by \fItv\fP and returns the value of \fItv\fP. .SH SEE ALSO .BR ares_fds (3), .BR ares_process (3), .BR ares_process_fd (3)
