Answer 1

The windows socket stack must first be initialized by a call to WSAStartup() first with the version of the windows lib you want to use (normally 2.0) Look it up for exact syntax.



If you've done that, try using WSAGetLastError() to get a explication of why the call failed.



good luck!

Answer 2

-1 indicates an error.

If it was opened correctly, you would have a socket descriptor returned by the function.

show code examples of the client and server sides of a socket connection.

Answer 3

Is your server socket listening?
