netErrNoInterfaces (is netlib emulation turned on in poser?)
-----------------
The number is a decimal number which you can look up in the 3.4
headers (in this case System/NetMgr.h).
Here is a code fragment from a similar app I wrote:
err = SysLibFind("INet.lib", &INRef);
INetLibConfigIndexFromName(INRef, inetCfgNameCTPDefault, &CfIn);
err = INetLibOpen(INRef, CfIn, 0, 0, 0, &inh);
set = 64000;
err |= INetLibSettingSet(INRef, inh, inetSettingMaxRspSize, &set, 4);
set = ctpConvNone;
err |= INetLibSettingSet(INRef, inh, inetSettingConvAlgorithm, &set, 4);
err |= INetLibURLOpen(INRef, inh, host, NULL, &sock, 2000, 0);
My next call is the sock read (after verifying err).
POSEr needs the network emulation turned on, but then the open call
will ALWAYS succeed. I think the URLOpen will not send or receive any
packets until the SockRead function is called.
If your URL is invalid in any way you can get errors too.
Also, if the Proxy server is down (slow, or has other problems) you
can get these errors (running a packet sniffer or a PPP that has this
kind of function helps since you can see the request and response).
You will note I set things so I can receive large files and get them
without proxy compression (bad things happen to binary data if you
don't). If your server is saying other than text/plain or text/html
it can also cause problems.
Since I don't know what you are doing ("Why did X stop working with
error Y" doesn't really help me diagnose things") I can't be more
specific.
