This is a standalone component of hvn3-engine intended for getting information about the runtime environment of the program.
OperatingSystemDefs.h defines HVN3_OS_WINDOWS on Windows, HVN3_OS_MACOS on MacOS, HVN3_OS_LINUX on Linux, HVN3_OS_UNIX on Unix, and HVN3_OS_FREEBSD on FreeBSD, providing an easy way to determine the current operating system without having to check for various standard and non-standard definitions.
It also defines HVN3_OS_X64 on 64-bit operating systems, and HVN3_OS_X86 on 32-bit operating systems. To detect Unix-based operating systems generically, HVN3_OS_UNIX_BASED is also defined on Unix-based platforms.
Environment.h offers a cross-platform interface for getting information about the runtime environment, including the current user's user name, the number of processors on the current machine, and the amount of memory mapped to the current process.
OperatingSystem.h contains declarations for platform enumeration types and the PlatformInfo class. The OperatingSystemInfo function returns a PlatformInfo instance containing information such as the current platform, platform name, and platform version.
