Load the operating system name, version name and patch name into the specified osName, osVersion and osPatch respectively. Return 0 on success and a non-zero value otherwise. The loaded values may represent an emulation provided for the current process (see "manifest-based behavior" in Windows programming documentation for an example) and therefore are not suitable for determining supported features or the real environment/version. If you need to determine the presence of certain features please consult the documentation of the operating systems you need to support.
