View the official Windows Driver Kit DDI referenceNo description available.
The FsRtlInsertPerStreamContext routine associates a file system filter driver's per-stream context structure with a file stream.
PerStreamContextPointer to the FSRTL_ADVANCED_FCB_HEADER structure for the file stream. To get this pointer from a file object, use the FsRtlGetPerStreamContextPointer macro.
Ptr [in]Pointer to a FSRTL_PER_STREAM_CONTEXT structure that the filter driver has allocated and initialized. To initialize this structure, use the FsRtlInitPerStreamContext macro.
FsRtlInsertPerStreamContext returns one of the following NTSTATUS values:
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The call to FsRtlInsertPerStreamContext was successful. |
| STATUS_INVALID_DEVICE_REQUEST | The underlying file system does not support filter contexts. |
A file system filter driver calls FsRtlInsertPerStreamContext to associate its own per-stream context structure with a file stream. The per-stream context structure contains context information that the filter driver maintains for the file stream.
After the per-stream context structure has been associated with a file stream, it can be retrieved by calling FsRtlLookupPerStreamContext or removed by calling FsRtlRemovePerStreamContext.
