A C++ library which contains C++20/Qt/CMake aid classes/scripts. The documentation is somewhat lacking, but all classes have unittests and should therefore function as documentation.

If somebody else, besides me 😉, should actually use the AidKit-library, let me know and I start working on the documentation.

Some notable classes:

• data_mutex: Wrapper around a thread shared resource which ensures at comple time, when accessing the resource, the corresponding mutex is locked.
• file: A RAII wrapper around std::FILE * functions. It also returns or throws a std::error_code instead of setting std::errno.
• file_error: A customized std::error_code for the above mentionded file class.
• file_ptr: A simple alias for a std::unique_ptr<> with a custom deleter which closes the std::FILE *.
• enum_class: A Java inspired enum class which allows searching/printing etc.
• enum_flags: Define flags like enums and test it with normal bit test operations.
• errno.hpp: Create a std::error_code from errno.
• system_error: Utility functions for throwing a std::system_error when an std::error_code was returned.

• DirectoryGuide/DirectoryVisitor: Allow traversing a directory tree.
• hton/ntoh: Functions to convert from host to network byte order and vice versa based on the size of the type.

• CMakeLists.txt: A (hopefully) exemplary CMake build script for a library build.
• output_options.cmake: Build all targets into the build directory.
• rpath_options.cmake: Setup rpath so shared libraries are searched in the current directory (and ./lib for Qt libraries).
