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.
