stange problem with bind() funcktion - winsock2

[s_4]

Hello!
Sorry about my english - I write to you from poland.
I have strange problem. Bind() return '16'. Documentation say that it
should return 0 (no error) or -1 (some error).

Here is the code of client.

Please help!

One more thing. Please do not use informal language. I may not
understand it.

Sorry about my english - I write to you from poland.
I have strange problem. Bind() return '16'. Documentation say that it
should return 0 (no error) or -1 (some error).

<some Windows specific C++ code snipped>

Sorry, but not only is your code totally system specific, so you
should ask in some Windows newsgroup, moreover it's not even C but
obviously C++. But what we're discussing here is the language C,
not C++ (there's comp.lang.c++ for that, but you should go to a
Windows specific group anyway since your problem doesn't seem to
be about C++ but about some system specific extensions to C++).

Regards, Jens

In addition to what the others have said, try to derive a minimal
compilable subset of your code that still exhibits your problem. As it
stands, your code is a bit too long for many posters to bother
verifying.

its more C style code than C++ tbh
strange mixture of using printf and cout, try to stick to one at least!

It should be in c++ but I have to write with winsock2, and in winsock
documentation there is meny things from c. Main socket funcktions are
from c so Im asking here. I have never programing in c and I have
programing in c++ for abuot 1 year. So I dont know exactly what is the
diference between c and c++. Many functions are simlar, I think or
even they are rewrite from c to c++.
Thank you for answer on my problem.

PS. Its write in Dev-cpp compilator so if you want to compile it in
dev-cpp you should add two librarys libwsock.a and libws2_32.a in
project options...

Thank you once again.

They are not from C they are from Windows. So, as you were told, you
need to ask in a Windows group of some sort.
