2. What exactly is Socket - Stack Overflow

   stackoverflow.com/questions/16233193

   A server runs on a specific computer and has a socket that is bound to a specific port number. The server just waits, listening to the socket for a client to make a connection request. When the server accepts the connection, it gets a new socket bound to the same local port and also has its remote endpoint set to the address and port of the client.

   A socket is a special type of file handle which is used by a process to request network services from the operating system.

4. python - Where is the _socket file? - Stack Overflow

   stackoverflow.com/questions/37475151

   The socket.py module wraps this with some additional information that doesn't need the speed boost or access to OS-level C APIs. If you are versed in C, you can read the socketmodule.c source code. There is no one-on-one mapping between the final .so or .dll file and the original source file however. You can grep the setup.py file for the names ...

7. Socket Programming in C++ - Stack Overflow

   stackoverflow.com/questions/3509011

   There is no socket API in the C++ Standard. The POSIX C API is fairly portable (the GNU libC documentation provides examples of UDP and TCP clients and servers that I usually turn to when I'm scratching together another server), or you could use the Boost.ASIO library for a more C++ experience....

    What do you mean by "not always reliable"? If the system succeeds in setting your socket non non-blocking, it will be non-blocking. Socket operations will return EWOULDBLOCK if they would block need to block (e.g. if the output buffer is full and you're calling send/write too often).

11. c - socket connect() vs bind() - Stack Overflow

    stackoverflow.com/questions/27014955

    The one liner : bind() to own address, connect() to remote address. Quoting from the man page of bind(). bind() assigns the address specified by addr to the socket referred to by the file descriptor sockfd. addrlen specifies the size, in bytes, of the address structure pointed to by addr.
