- * SHCopyKeyA	[SHLWAPI.@]

- * Copy a key and its values/sub keys to another location.
- *
- * PARAMS
- *  hKeySrc    [I] Source key to copy from
- *  lpszSrcSubKey [I] Sub key under hKeySrc, or NULL to use hKeySrc directly
- *  hKeyDst    [I] Destination key
- *  dwReserved [I] Reserved, must be 0
- *
- * RETURNS
- *  Success: ERROR_SUCCESS. The key is copied to the destination key.
- *  Failure: A standard windows error code.
- *
- * NOTES
- *  If hKeyDst is a key under hKeySrc, this function will misbehave
- *  (It will loop until out of stack, or the registry is full). This
- *  bug is present in Win32 also.
