int ZwQueryKey(WinNT.HANDLE KeyHandle, int KeyInformationClass, Structure KeyInformation, int Length, IntByReference ResultLength)
KeyHandle
- Handle to the registry key to obtain information about. This handle is created by
a successful call to ZwCreateKey or ZwOpenKey.KeyInformationClass
- Specifies a KEY_INFORMATION_CLASS value that determines the type of information
returned in the KeyInformation buffer.KeyInformation
- Pointer to a caller-allocated buffer that receives the requested information.Length
- Specifies the size, in bytes, of the KeyInformation buffer.ResultLength
- Pointer to a variable that receives the size, in bytes, of the requested key
information. If ZwQueryKey returns STATUS_SUCCESS, the variable contains the amount
of data returned. If ZwQueryKey returns STATUS_BUFFER_OVERFLOW or
STATUS_BUFFER_TOO_SMALL, you can use the value of the variable to determine the
required buffer size.
