RegQueryReflectionKey function (winreg.h)
Determines whether reflection has been disabled or enabled for the specified key.
Syntax
LONG RegQueryReflectionKey(
[in] HKEY hBase,
[out] BOOL *bIsReflectionDisabled
);
Parameters
[in] hBase
A handle to the registry key. This handle is returned by the RegCreateKeyEx, RegCreateKeyTransacted, RegOpenKeyEx, or RegOpenKeyTransacted function; it cannot specify a key on a remote computer.
[out] bIsReflectionDisabled
A value that indicates whether reflection has been disabled through RegDisableReflectionKey or enabled through RegEnableReflectionKey.
Return value
If the function succeeds, the return value is ERROR_SUCCESS.
If the function fails, the return value is a nonzero error code defined in Winerror.h. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description of the error.
Remarks
On WOW64, 32-bit applications view a registry tree that is separate from the registry tree that 64-bit applications view. Registry reflection copies specific registry keys and values between the two views.
To disable registry reflection, use the RegDisableReflectionKey function. To restore reflection for a disabled key, use the RegEnableReflectionKey function.
