WHAT IS LLNL MCAST?:

    The LLNL MCAST software is an experimental implementation of a
    multicast communication system.  It allows applications to communicate
    in a broadcast-like manner with other applications.  Multicast would
    typically be used by the parts of a distributed application.

    The system consists of an application programming interface (API)
    modeled on the Berkeley socket abstraction, a communications server,
    and a complete set of manual pages.

    The communication server implements the multicast message passing
    semantics.  A version of the system which uses network level multicast
    facilities is planned, but we needed something up and running quickly
    so other members of our project team could proceed with their work.
    Hence, this version.  Our goal is to be able to slip in a true
    multicast implementation using the same API under our applications
    without the applications noticing the difference ...

Regarding: Memo of understanding for release of ``MCAST'' software
X
X
Marliss,
X
You asked me to tell you why I want do an unrestricted release of the
MCAST multicast testbed software I developed.  There are two fundamental
reasons:
X
X    1.    My software software is simple enough that it will allow people to
X    experiment with multicast concepts without getting bogged down in
X    one of the already existing multicast packages.  Those existing
X    packages are all enormous and complicated -- although far more
X    sophisticated and more complete than my package.
X
X    Because of the large amount of startup effort needed to use
X    existing packages, there isn't a widespread general interest in
X    multicast.  Thus, I think that distributing my software will
X    benefit the network research community by exposing more people to
X    multicast concepts.
X
X    2.    This is the equivalent of publishing a paper for me.  It will
X    gain me recognition and advance my career.
X
X
X                    Yours sincerely,
X
X                    Leith (Casey) Leedom

X
X
HOW TO INSTALL MCAST:
X
X    PORTABILITY:
X
X        Where possible, this software has been written to conform to
X    ANSI C as defined in ANSI X3.159-1989 and POSIX 1003.1 as
X        defined in IEEE Std 1003.1-1990.  Unfortunately there are no
X        standards available yet for networking APIs.  Where we were
X        forced to step beyond the ANSI C and POSIX 1003.1 standards,
X        we chose to use the BSD (Berkeley Software Distribution)
X        definitions.  As such, it depends on the BSD socket
X        facilities, I/O control mechanisms, select, etc.
X
X        At the time of this writing the software has been compiled and
X    tested on IBM RS6000s running AIX 3.2, SGIs running IRIX 4.0.1
X    and Suns running SunOS 4.1.1.
X
X    All the configuration information is contained in the file
X    "config/Makefile.config."  The configuration scheme is grossly modeled
X    on the X11 imake scheme, but without imake ...  (I told you it was
X    gross.)
X
X    In any case, each directory contains two Makefiles: "Makefile" and
X    "Makefile.tmpl."  The Makefile basically reinvokes make for all
X    targets with roughly the following command:
X
X        make -f $(TOP)/config/Makefile.config \
X             -f ./Makefile \
X             -f $(TOP)/config/Makefile.std
X
X    The Makefile.tmpl contains all the real make commands to generate and
X    install the contents of the current directory.
X
X    You may also have to change the MCD_SERVICE_PORT constant in
X    include/netmcast/mcastd.h if the default port, 8001, conflicts with a
X    port already in use on your system.  This constant controls the
X    default port the multicast server uses.
X
X    After editing config/Makefile.config (and possibly mcastd.h), type
X    the following in the top level directory:
X
X        host-foo% make clean
X        host-foo% make
X
X    TESTING THE SYSTEM:
X
X        If everything went okay, you should now have a working system.  To
X        test it, try the following:
X
X        In one window, type:
X            host-foo% cd mcastd
X            host-foo% ./mcastd -d -l 7
X        (This will start up the multicast server on host-foo.)
X
X        In second window, type:
X            host-bar% cd test
X            host-bar% setenv MCASTD_SERVER host-foo
X            host-bar% ./mc_listen snee
X        (This will start a small test application up, that listens to
X         multicast group "snee" and outputs any messages it receives onto
X         standard output.)
X
X        Finally, in a third window, type:
X            host-baz% cd test
X            host-baz% setenv MCASTD_SERVER host-foo
X            host-baz% ./mc_clock snee
X        (This will start a second small test application up, that emits an
X         ASCII date/time stamp onto the multicast group snee every five
X         seconds.)
X
X        What you should see is copious amounts of output in the window you
X        started mcastd in.  It will register nearly every action that it's
X        taking.  In the mc_listen window, you should see a data/time stamp
X        appearing once every five seconds.
X
X        If you want, you can start up multiple listener processes, using
X        the same or different multicast groups, and the same with the clock
X        processes.  You can also start up a sender processes, mc_send,
X        which copies standard input to a specified multicast group.
X
X        For giggles, there's the ubiquitous hello world program, mc_hello,
X        which simply emits the message "hello world!" onto the multicast
X        group "hello-world-group".  This is an especially fun application
X        because it shows just how short a working multicast application can
X        be.  Not counting comments, it's 18 lines long, two of which are
X        blank and three of which are error recovery.
X
X        Finally, there's an incomplete version of the nearly as ubiquitous
X        ping program, mc_ping.  This program opens a connection to a
X        specified multicast group and sends itself messages in order to
X        measure the round trip time through the multicast server, mcastd.
X        This would be more complete if it allowed one to ping a specified
X        recipient application, say, ``pong,'' to measure application to
X        application round trip time, but other projects were pressing ...
X
X    Once you're happy with the software and want to install it on your
X    system, just type the following in the top level directory:
X
X        host-foo% make install
X        host-foo% make clean
X
X
WHERE TO GO FROM HERE:
X
X    Hopefully the test programs in the "test" subdirectory should serve as
X    useful trivial examples.  At least I always find it easier to steal
X    code than to read manual pages. :-)
X
X    If you find yourself overcome with an urge to RTFM, a complete set of
X    manual pages has been provided.  You should probably start with
X    mcast.4, move on to mcast_sopen.3, and finally mc_read.2 and
X    mc_write.2.  Once you feel comfortable with those, you should probably
X    attack mc_socket.2, mc_bind.2, mcast_newaddr.3, and
X    mcast_getgroupbyname.3.  Mcast_sopen takes much of the pain out of
X    setting up a multicast socket and basically just calls mc_socket,
X    mcast_newaddr, mcast_getgroupbyname, and mc_bind for you.
X
X    The file ABSTRACT contains a summary abstract of this software.  It
X    is used by LLNL's software release program to help catalogue software
X    in a standard form.  Similarly, the file MEMO is also part of LLNL's
X    software release process and contains a ``memo of understanding''
X    describing why I wanted to release this software.
X
X    The file TODO in the top level directory contains a brief set of notes
X    describing things left to finish in the implementation.  The file
X    doc/notes.me contains a set of implementation notes about the multicast
X    abstraction we provide, the API, and our experiences.  The file
X    doc/cover.me is a short introduction and table of contents which we use
X    when we put together a bound documentation and source printout.

X
X              UNFINISHED WORK ON THE LLNL MCAST DISTRIBUTION
X
X
X    o    Implement a real naming scheme: registration and lookup.  Currently
X    mcast_getgroupbyname just zeros out a multicast address and then
X    strncpy copies the group name into the address.  Pretty hokey, but
X    it let us get started.
X
X    o    Implement the readv and writev limcast routines.  This will require
X    rewriting the _mc_read and _mc_write low level routines to accept
X    a uio structure.  Obviously all the mc_read, mc_write, mc_recv,
X    mc_send, etc. routines will also have to be modified to follow
X    suit.
X
X    o    Implement a way to get the current multicast group membership and
X    also a way to get asynchronous notification of group membership
X    changes.
X
X    o    Write general documentation covering multicast abstraction and
X    interface.
X
X    o    Write up implementation notes for the internal structure of the
X    multicast server.  Diagrams describing the varied data structures
X    would be especially nice ...
X
X    o    Well, obviously a true multicast implementation would be nice too ...

X# Operating system/platform specific values:
X#
X# IBM AIX 3.2:
X#   1.    STD_DEFINES should contain -qlanglvl=ansi -D_ALL_SOURCE -D_BSD.
X#   2.    CDEBUGFLAGS should contain -qsrcmsg.  It should probably also contain
X#    -qextchk, but that causes the loader to complain about a type
X#    mismatch for mc_fcntl between mc_fcntl.c and mc_ioctl.c in
X#    libmcast when you try to link against the library.  This is
X#    completely bogus.  CDEBUGFLAGS should also probably contain -g or
X#    -O depending on your debugging/performance needs.
X#   3.    Set RANLIB to /bin/true.
X#
X# SGI IRIX 4.0:
X#   1.    CDEBUGFLAGS should contain -prototypes in order to get C function
X#    prototype checking.  CDEBUGFLAGS should also probably contain -g
X#    or -O depending on your debugging/performance needs.
X#   2.    Set RANLIB to /bin/true.
X#
X# SUN OS 4.1.1:
X#   1.    CC should be an ANSI C compiler like gcc or Sun's unbundled compiler.
X#    Sun's bundled compiler won't work.
X#   2.    If gcc is used, you'll probably have to add -I/usr/include to
X#    STD_INCLUDES because gcc seems to search its own local include
X#    directory before /usr/include which leads to all sorts of problems.
X#   3.    Add -DNEED_STRERROR, -DNEED_OFFSETOF, -DNEED_EXIT_CODES and
X#    -DBROKEN_INET_NTOA to STD_DEFINES.  Sun OS 4.1.1 fails to supply
X#    the ANSI C X3.159-1989 strerror routine, the offsetof macro and the
X#    EXIT_SUCCESS and EXIT_FAILURE defines.  It also changes inet_ntoa
X#    to take a *pointer to* a struct in_addr instead of the struct itself
X#    (which it fails to document in the manual page).
X#   4.    CDEBUGFLAGS should also probably contain -g or -O depending on your
X#    debugging/performance needs.
X#   5.    Set RANLIB to ranlib.

X.SH NAME
mc_close \- delete a multicast socket descriptor
X.SH SYNOPSIS
X.nf
X.ft B
X#include <unistd.h>
X#include <sys/types.h>
X#include <sys/socket.h>
X#include <netmcast/mcast.h>
X
int
mc_close(int s)
X.ft P
X.fi
X.SH DESCRIPTION
The
X.IR mc_close (2)
call deletes a multicast socket descriptor from the per-process object
reference table.
If this is the last reference to the underlying object, the
object will be deactivated.
X.SH COMPATIBILITY
The
X.I mc_close
call emulates the
X.IR close (2)
system call for multicast socket descriptors created with the
X.IR mc_socket (2)
call.
See the manual page for
X.IR close (2)
for a description of the emulated semantics.
X.I Mc_close
does not provide any different semantics from
X.IR close (2).
X.SH "RETURN VALUES"
Upon successful completion, a value of 0 is returned.
Otherwise, a value of -1 is returned and the global integer variable
X.I errno
is set to indicate the error.
X.SH ERRORS
See the manual page for
X.IR close (2)
for a detailed list of errors associated with the general
X.IR close (2)
system call.
X.I Mc_close
itself will fail if:
X.TP 20
X[EBADF]
X.I S
is not a valid multicast socket descriptor as returned by
X.IR mc_socket (2).
X.SH "SEE ALSO"
X.IR close (2),
X.IR mc_socket (2),
X.IR mcast (4)
X.SH STANDARDS
There are no current standards that address multicast communication.
The software described in this manual page is experimental and subject
to change at any time.

X.SH NAME
mc_shutdown \- shut down part of a full-duplex connection
X.SH SYNOPSIS
X.nf
X.ft B
X#include <sys/types.h>
X#include <sys/socket.h>
X#include <netmcast/mast.h>
X
int
mc_shutdown(int s, int how)
X.ft P
X.fi
X.SH DESCRIPTION
The
X.I mc_shutdown
call causes all or part of a full-duplex connection on
the multicast socket associated with
X.I s
to be shut down.
If
X.I how
is 0, further receives will be disallowed.
If
X.I how
is 1, further sends will be disallowed.
If
X.I how
is 2, further sends and receives will be disallowed.
X.SH COMPATIBILITY
The
X.I mc_shutdown
call emulates the
X.IR shutdown (2)
system call for multicast socket descriptors created with the
X.IR mc_socket (2)
call.
See the manual page for
X.IR shutdown (2)
for a description of the emulated semantics.
X.I Mc_shutdown
does not provide any different semantics from
X.IR shutdown (2).
X.SH "RETURN VALUES"
Upon successful completion, a value of 0 is returned.
Otherwise, a value of -1 is returned and the global integer variable
X.I errno
is set to indicate the error.
X.SH ERRORS
See the manual page for
X.IR shutdown (2)
for a detailed list of errors associated with the general
X.IR shutdown (2)
system call.
X.I Mc_shutdown
itself will fail if:
X.TP 20
X[EBADF]
X.I S
is not a valid multicast socket descriptor as returned by
X.IR mc_socket (2).
X.TP 20
X[EIO]
The socket state has become corrupted.  This is an artifact of a
client/server implementation of the multicast communication system.
X.SH "SEE ALSO"
X.IR mc_connect (2),
X.IR mc_socket (2),
X.IR mcast (4),
X.IR shutdown (2)
X.SH STANDARDS
There are no current standards that address multicast communication.
The software described in this manual page is experimental and subject
to change at any time.
