RxInferFileType tries to infer the file type (directory or non-directory) from a member in the RX_CONTEXT structure.
RxContext [in]A pointer to the RX_CONTEXT structure.
RxInferFileType returns the storage type implied by the open.
| Return code | Description |
|---|---|
| FileTypeDirectory | The file type is a directory. |
| FileTypeFile | The file type is a file. |
| FileTypeNotYetKnown | The file type could not be determined. If RxInferFileType cannot determine the file type, this routine returns this value. |
RxInferFileType tries to infer the file type (directory or non-directory) from the Create.NtCreateParameters.CreateOptions member in the RX_CONTEXT structure.
The RxInferFileType routine is not called internally by RDBSS. The RxInferFileType routine might be used as a helper routine by a network mini-redirector driver in the MRxCreate routine provided by the network mini-redirector. MRxCreate would normally be called when an I/O request packet is received for IRP_MJ_CREATE. This IRP is normally received by RDBSS in response to a user-mode application requesting a file open or create operation. It is also possible for another kernel driver to issue such an IRP.
