masesk / easy-socket Goto Github PK

• Add an example of how to use the library wrapper in the read me
• Add instructions on how to build and include for Linux
• Fix std to masesk for using namespace example

Since this library is intended to work on Windows/Linux, it might be prudent to add CMake support for the library so I can be built natively on Linux by users if they so choose. If this is desired I can file a PR.

Thanks!

When trying to use socketListen on the clients application the window stops responding. Is this because it is exclusively used for the server? Or am I able to use socketListen and socketSend on either side of the app. I am able to send the code but I will have to cut out a lot of the random other stuff since it's being used for a game.

I'm testing a simple client call.

To test the exception, I call socketConnect() without an actual server to connect to.

But in my try/catch I am not able to catch the socket_error_exception. My code:

try
{
	client->socketConnect("io_update", "127.0.0.1", 50051);
}
catch(const masesk::socket_error_exception& e)
{
	return -3;
}

will just terminate the program, without catching anything.

I looked at your code:

void socketConnect(const std::string &channelName, const std::string &ip, std::uint16_t port)
{
	if (sockInit() != 0)
	{
		throw masesk::socket_error_exception();
		return;
	}
	SOCKET sock = socket(AF_INET, SOCK_STREAM, 0);
	if (sock == INVALID_SOCKET || sock == SOCKET_ERROR)
	{
		sockQuit();
		throw masesk::socket_error_exception();
	}
	sockaddr_in hint;
	hint.sin_family = AF_INET;
	hint.sin_port = htons(port);
	inet_pton(AF_INET, ip.c_str(), &hint.sin_addr);
	int connResult = connect(sock, (sockaddr *)&hint, sizeof(hint));
	if (connResult == SOCKET_ERROR)
	{
		sockClose(sock);
		sockQuit();
		throw socket_error_exception();
	}
 ...

and noticed that sockQuit() will actually return 0 before the throw. Would that be a problem?

Thanks

Everything passed to the wrapper should be a pass by const-referrence instead of pass-by value.
