InetAPI

InetAPI is an internet access API following the Stratify Labs API framework.

It includes sub-projects which will build LWIP as well as pull and build mbedtls from the Github repository.

How to Build

The InetAPI library is designed to be a CMake sub-project. To build, please use one of these projects:

Desktop Command Line Interface
Stratify OS on Nucleo-144

Usage

Sockets

You can use a Socket or a SecureSocket. The latter uses mbedtls for secure connections. The Socket layer is a C++ wrapper for POSIX style sockets (works on Stratify OS, Windows, macOS and Linux).

#include <inet.hpp>

//HTTP server with sockets
AddressInfo address_info(AddressInfo::Construct()
                              .set_family(Socket::Family::inet)
                              .set_service(NumberString(self->m_server_port))
                              .set_type(Socket::Type::stream)
                              .set_flags(AddressInfo::Flags::passive));

const SocketAddress &server_listen_address = address_info.list().at(0);
Socket server_listen_socket =
    Socket(server_listen_address)
        .set_option(SocketOption(Socket::Level::socket,
                                  Socket::NameFlags::socket_reuse_address))
        .bind_and_listen(server_listen_address)
        .move();

HTTP Server

#include <inet.hpp>

      .run(this,
            [](HttpServer *server, void *context,
