* MsiQuery.h - Interface to running installer for custom actions and tools *
* *
* Version 2.0 *
* *
* NOTES: All buffers sizes are TCHAR count, null included only on input *
* Return argument pointers may be null if not interested in value *
* Returned handles of all types must be closed: MsiCloseHandle(h) *
* Functions with UINT return type return a system error code *
* Designated functions will set or clear the last error record, *
* which is then accessible with MsiGetLastErrorRecord. However, *
* the following argument errors do not register an error record: *
* ERROR_INVALID_HANDLE, ERROR_INVALID_PARAMETER, ERROR_MORE_DATA. *
