An OS API/system call library #5206
Description
Is your feature request related to a problem? Please describe.
Many libraries, like the Win32 API or POSIX C libraries, are C libraries and require arcane knowledge of ancient APIs to interact with the operating system with. This makes it difficult or even requiring un-idiomatic, C-style code in otherwise C++-style projects.
Describe the solution you'd like
I would like like to see C++ wrappers and OOP-style wrappers for calling operating system APIs, including Windows, macOS, and Linux (something like Poco::Platform::*, Poco::Platform::Win32::* or Poco::Platform::Windows::*, Poco::Platform::Posix::*, etc.) which provide improved facilities to interact with the operating system or make system calls.
Describe alternatives you've considered
There are some wrapper libraries for C++ for POSIX, but they are extremely obscure and probably abandoned. For Windows, there is win32metadata (for languages other than C, but apparently not C++) cppwinrt (based on C++17, but has apparently been put in maintenance mode and won't receive any new features). I thought it might be possible that Boost C++ libraries might have something like this, but it seems not.
Additional context
It might be worthwhile also integrating some of the features from boost::system, which has its own way for wrapping errors over a platform-agnostic API.
While it seems there is already some ability to manipulate the Windows Registry (Poco::Util::WinRegistryConfiguration, Poco::Util::WinRegistryKey, Poco::Util::WinService) as well as Poco::SyslogChannel for interacting with the Unix syslog service, what I am proposing is intended for additional control over platform-specific services. It might be worth moving these classes in to this namespace as well (or aliasing with using statements).
