File descriptors already +set in \fIread_fds\fP and \fIwrite_fds\fP will remain set; initialization of +the file descriptor sets (using \fBFD_ZERO\fP) is the responsibility of the +caller. +.SH RETURN VALUES +\fBares_fds(3)\fP returns a value that is one greater than the number of the +highest socket set in either \fIread_fds\fP or \fIwrite_fds\fP. If no queries +are active, \fBares_fds(3)\fP returns 0. +.SH SEE ALSO +.BR ares_timeout (3), +.BR ares_process (3) +.SH AUTHOR +Greg Hudson, MIT Information Systems +.br +Copyright 1998 by the Massachusetts Institute of Technology. -- cgit v1.2.3
