ICCcommand(cmd, argv, replyp)
extern char *ICCfailure;
The routines described in this manual page are part of the InterNetNews
They are used to send commands to a running
daemon on the local host.
The letters ICC stand for
ICCopen creates a
Unix-domain datagram socket and binds it to the servers control socket, if
<HAVE_UNIX_DOMAIN_SOCKETS in include/config.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.
ICCsettimeout can be called before any of the following routines to determine how long
the library should wait before giving up on getting the servers reply.
This is done by setting and catching a SIGALRM
If the timeout is less then zero then no reply will be waited for.
The SC_SHUTDOWN, SC_XABORT, and SC_XEXEC commands do not get a reply either.
The default, which can be obtained by setting the timeout to zero, is to
wait until the server replies.
ICCcommand sends the command
cmd with parameters
argv to the server.
It returns -1 on error.
If the server replies, and
replyp is not NULL, it will be filled in with an allocated buffer that contains
the full text of the servers reply.
This buffer is a string in the form of <digits><space><text>
where digits is the text value of the recommended exit code;
zero indicates success.
Replies longer then 4000 bytes will be truncated.
The possible values of
cmd are defined in the inn/inndcomm.h header file.
The parameters for each command are described in
This routine returns -1 on communication failure, or the exit status
sent by the server which will never be negative.
ICCcancel sends a cancel message to the server.
Mesgid is the Message-ID of the article that should be cancelled.
The return value is the same as for
ICCgo send a pause, reserve, or go command to the server, respectively.
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
The return value for all three routines is the same as for
If any routine described above fails, the
ICCfailure variable will identify the system call that failed.
