Method Detail

ZwQueryKey

int ZwQueryKey(WinNT.HANDLE KeyHandle,
               int KeyInformationClass,
               Structure KeyInformation,
               int Length,
               IntByReference ResultLength)

The ZwQueryKey routine provides information about the class of a registry key, and the number and sizes of its subkeys.

Parameters:

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.

Returns:

ZwQueryKey returns STATUS_SUCCESS on success, or the appropriate error code on failure.
