Hi Tom,

i have made a first, tiny quick hack of a C based SOCKET client.
It should compile on Windows and Linux.

It currently supports only synchronous access like

connect, publish, unSubscribe, erase, disconnect

and reports exception nicely back to the client.

If you think this is a way for you to follow please check out the
newest xmlBlaster from cvs. You need to compile the xmlBlaster Java
server as well as i did some relaxing checks in the SOCKET server.

Then try the client:

cd xmlBlaster/demo/c/socket   (see client.c)

Linux:          gcc -Wall -g -o client client.c callbackServer.c -lpthread

Windows:  cl /MT /W3 /Wp64 -D_WINDOWS client.c callbackServer.c ws2_32.lib


Now start xmlBlaster:

java org.xmlBlaster.Main -dump[socket] true -trace[socket] true 
-call[socket] true  -call[core] true

and the C client:

client

The client connects and does some invocations (see the main() in client.c).

The code is plain C so it should be possible to compile it on all your 
platforms
and it has only 19 kBytes size on Linux.

If this is a solution for your we would need to:

o Clean up the code
 - move to xmlBlaster/src/c
 - split to files
 - make a lib from it

o Make layers of functionality
 - raw communication
 - adding threading support to allow callbacks in the same process.
 - expat parsing

o Add some demo in xmlBlaster/demo/c

o Wrap it as a C++ protocol plugin to be independend of CORBA and
 use the C++ testsuite for this C implementation

regards,

Marcel
