NAME

       ares_fds - Get file descriptors to select on for name service

SYNOPSIS

       #include <ares.h>

       int ares_fds(ares_channel channel, fd_set *read_fds,
       fd_set *write_fds)

DESCRIPTION

       The  ares_fds function retrieves the set of file descriptors which the calling application
       should select on for reading and writing  for  the  processing  of  name  service  queries
       pending  on  the name service channel identified by channel.  File descriptors will be set
       in the file descriptor sets pointed to by read_fds and  write_fds  as  appropriate.   File
       descriptors  already  set in read_fds and write_fds will remain set; initialization of the
       file descriptor sets (using FD_ZERO) is the responsibility of the caller.

RETURN VALUES

       ares_fds returns one greater than the number of the highest socket set in either  read_fds
       or write_fds.  If no queries are active, ares_fds will return 0.
