Maybe something like this:

int family = AF_INET;
int type = SOCK_STREAM;
int zero = 0;

sock = socket (&family, &type, &zero);

When you say hangs, do you mean hangs waiting for something or hangs stuck
in an infinte loop?

This is a complete wild guess.? Maybe CARGENV causes arguments passed by
value to socket routines to be somehow changed into arguments passed by
reference?? How about trying something like this as a test:

sock = socket (&AF_INET, &SOCK_STREAM, &0);

and see if it still hangs?

Maybe the MUSIC debugger could be used to get more details on what is
going wrong?? It might even be possible to figure out in what way the
arguments being passed to socket() from C are "wrong" which might in
turn allow a replacement for CARGENV to be written?

Peter Coghlan.

I would use sock = socket (AF_INET, SOCK_STREAM, IP_PROTO_TCP);
or something like that.

I can't help you more because I didn't manage to make TCPIP available yet in my Hercules.
Not sure if it's possible.

The reason I ask is this, from the readme.txt in the musdemo_b download:

"You can also run the MUSIC/SP Demo system under the Hercules mainframe

emulator, but in that case none of the tcp/ip applications in MUSIC/SP

can be used, such as FTP, FTPD, HTTPD, socket programming, etc."

I am trying to port over a server program in "C", to MUSIC/SP using WATC?? In the AR guide, part-3
page 228, the following is referenced:

.If you wish to code socket application in C, you must include a call to CARGENV (no parameters required)
in order to cause the socket routines to automatically convert the arguments passed to assembler calling
conventions. In this case, use the normal C calling conventions as defined by the SOCKET.HDR header file.

I can find NO reference anyway else about CARGENV.? and of course by server program will not work
on MUSIC/SP.? Any direction or info on how to use or where to find info on CARGENV, would be
very helpful.

Thank You
