return value
Returns Error_Success if the call is successful.
If the call fails, returns a non-zero error code (defined in WineError.h). You can use the format_message_from_syste tag formAtMessage function to get normal error description information.
note
This given handle should not be used after it shuts it because it is no longer valid. The key handle should not be shorter than the required time.
RegcloseKey does not need to write information in the registry before returning; it can take a few seconds to cache the cache area of the hard disk. If an application must write registration information to the hard disk, it can use the RegflushKey function. RegflushKey, however, more system resources should be called when necessary.
The Windows CE: RegLoseKey function always returns to write information to the registry, in Windows CE to remove the needs of the cache key.
