DESCRIPTION

       The routines described in this manual page are part of the InterNetNews
       library, libinn(3).  They are  used  to  send  commands  to  a  running
       innd(8)  daemon  on the local host.  The letters ``ICC'' stand for Innd
       Control Command.

       ICCopen creates a Unix-domain datagram  socket  and  binds  it  to  the
       server's  control  socket, if <HAVE_UNIX_DOMAIN_SOCKETS in include/con-
       fig.h> is defined.  Otherwise it creates a named pipe for communicating
       with  the  server.   It returns -1 on failure or zero on success.  This
       routine must be called before any other routine.

       ICCclose closes any descriptors that have been created by ICCopen.   It
       returns -1 on failure or zero on success.

       4000  bytes  will be truncated.  The possible values of cmd are defined
       in the ``inndcomm.h'' header file.  The parameters for each command are
       described  in  ctlinnd(8).   This  routine  returns -1 on communication
       failure, or the exit status sent by the server which will never be neg-
       ative.

       ICCcancel sends a ``cancel'' message to the server.  Mesgid is the Mes-
       sage-ID of the article that should be canceled.  The  return  value  is
       the same as for ICCcommand.

       ICCpause,  ICCreserve,  and  ICCgo  send  a  ``pause,'' ``reserve,'' or
       ``go'' command to the server, respectively.   If  ICCreserve  is  used,
       then  the  why  value  used  in the ICCpause invocation must match; the
       value used in the ICCgo invocation must always match that the one  used
       in the ICCpause invocation.  The return value for all three routines is
       the same as for ICCcommand.

       If any routine described above  fails,  the  ICCfailure  variable  will
       identify the system call that failed.
