IP Number Retrieval under WINE
on Mon, 16 Sep 2002 13:01:46 -0300

Hi!

I'm experimenting with the sample program provided by ASInet.
Attached are source code for SERVER.exe and ERROR.LOG generated by the App
running on WINE on RedHat Linux 7.3.
On the client side, running Win 98 SE, it runs OK.
To clear the concepts:
If the SERVER.PRG is compiled on Win98 and runs on Win98, it does it well.
If the same .EXE runs on WINE it gives the error detailed at ERROR.LOG.

The offending instruction seems to be:

cServerIP :=
SocketInetNtoA(SocketGetHostByName(SocketGetHostName())[HOSTINFO_ADDR,1])

The underlaying idea is to get the IP number of the server and/or Client.
Any ideas?

TIA

Regards

Jose Luis,

>The offending instruction seems to be:

>cServerIP :=
>SocketInetNtoA(SocketGetHostByName(SocketGetHostName())[HOSTINFO_ADDR,1])

According to the error log, the error occurred when you tried to access an
item of the aHostInfo array, but the previous line "SocketGetHostByName()"
apparently returned NIL, probably because of an error in that or a previous 
function, like "SocketGetHostName()".

Modify the test program, so it returns error codes -- this might shed some
light on the actual (Socket) error that occurred before. All those functions 
can return error codes - check the online help for details.

HTH,

It seems to be something related with WINE, due there is not such fail in
Win98 SE.

I'm adding some error code generation so it will do it as you wisely said.
Thanks for the tip.
