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) +.SH AUTHOR +Greg Hudson, MIT Information Systems +.br +Copyright 1998 by the Massachusetts Institute of Technology. |
