netry

Netry is a very simple high level networking library implementation of The Single UNIX Specification, Version 2.

Project

• Language: C++ 11 Standard
• IDE: CLion 2017.2.3
• Build: CMake 3.9

Functionality

• Server instance to wait for connections in a specific port.
• Socket instance to connect in a specific ip address and port.
• Data transfer between two endpoints using a connected socket for the types:
  • Byte
  • Integer
  • String

Possible Improvements

Allow listening in more than one port with the same ip address.
The sockaddr_in C struct can be initiated only once with one address, so when a new ServerSocket is instantiated, it throws an error.

Solutions:

• Keep a reference to every struct address sockaddr_in and, if it alreadt exists, use it to listen in a new port.
  
• Handle it in C level
