Universal cross-platform C99/C++ sockets library.

This library provides universal cross-platform network sockets implementation. Supports Windows (recommended MinGW UCRT64 env., MSVC also supported), and any other OS that provides POSIX socket implementation. Also this library supports both static & dynamic linking and building (if set CMake BUILD_SHARED_LIBS to ON).

Building the library

Windows

Requirements: MSYS2 UCRT64, MinGW UCRT64, make, CMake.

1. Run MSYS2 UCRT64 environment (recommended). Install all requirements if you haven't it.
2. Clone this repo and go to repository root folder.
3. Create folder build. Go to this catalog.
4. Run cmake -S .. -G "MinGW Makefiles" -DCMAKE_INSTALL_PATH=$MSYSTEM_PREFIX. Wait for generating Makefile.
5. Run mingw32-make and wait for building library.

Linux (UNIX)

Requirements: GCC, make, CMake

1. Install all requirements if you haven't it.
2. Clone this repo and go to repository root folder.
3. Create folder build. Go to this catalog.
4. Run cmake -S ... Wait for generating Makefile.
5. Run make and wait for building library.

Installation

Windows

Just run mingw32-make install. Library will be installed to your MSYS2 system path (specified in -DCMAKE_INSTALL_PATH CMake option; /ucrt64 in this example).

Linux (UNIX)

Also just run sudo make install. Library will be installed to your system.

Using in project

Include <libsocket.h> header where you need to use this library. That link your executable with library by adding flag to command line -lsocket. On Windows you already need to link you executable with WinSock2 library, so just add flag -lws2_32 command line. If you use static version of this library, please specify definition LIBSOCKET_STATIC when you compile file, where included libsocket header.

If you using CMake in your project, add libsocket by same method or with using find_package:

find_package(libsocket REQUIRED)
target_link_libraries(<target> PRIVATE libsocket::socket)

This will fully automatily setup libsocket for your project. By default CMake will use static version of libsocket, so if you want to use dynamic version of this library, set BUILD_SHARED_LIBS flag in your CMake config command prompt to ON.

Tests

Tests are available in /tests/ folder in the root of repo. You can also use they as examples.

All tests short description:

• Test 0 (0.c): HTTP 1.0 GET request test.
• Test 1 (1.c): Unsafe API functions (for ex. socket_gethandle) test.
