nes_sockets

Simple socket and secure socket in modern C++.

Non-blocking implementation of sockets for Windows and Linux for sequencial (not asynchronous) programming.

Requisites

• C++20

• OpenSSL Library

Building

This project uses CMake as build system. In directory ./build/ run:

cmake ..
cmake --build .

Will produce the static library in bin to link your program. You can configure another build systems in cmake options. And can also add the dependency if you use CMake as well.

Tests

Is used a homemade testing framework called qtest. To build the testing of nes_sockets use the CMake target nes_socket_test will link to the library and produces the executable nes_socket_test.

Example of sucessful run:

~/.../build$ ../bin/nes_socket_test
Automated Test Suite
Default path dir: ".../nes_sockets/bin"
### Test Summary ###
32 test executed in 1 package. (0 errors).

Example of failure:

~/.../build$ ../bin/nes_socket_test

Examples

In examples folder:

• http_get.cpp: show basic usage of sockets to use the HTTP protocol. CMake build target ex_http_get.

• tcp_echo_server.cpp: a echo server that listen to incoming conections. Prints the received data in terminal and sends back the same data. CMake build target ex_tcp_echo_server.
