);
View the official Windows Driver Kit DDI referenceNo description available.
The IoSetFileOrigin routine specifies whether a given file object is for a remote create request.
FileObject [in]Pointer to the file object.
Remote [in]Set to TRUE to set the FO_REMOTE_ORIGIN flag on the file object, FALSE to clear it.
If the FO_REMOTE_ORIGIN flag on the file object is not already set (or cleared) as specified by the Remote parameter, IoSetFileOrigin sets or clears the flag as appropriate and returns STATUS_SUCCESS.
If the flag is already set (or cleared) as specified, IoSetFileOrigin returns STATUS_INVALID_PARAMETER_MIX and does not set or clear the flag.
Network file systems call IoSetFileOrigin to set or clear the FO_REMOTE_ORIGIN flag on the file object pointed to by FileObject. This flag is set to indicate that the file object was created to satisfy a remote create request.
Network file systems should call IoSetFileOrigin in their servers for any file objects that are created to satisfy a create request from a network client.
File system filter drivers should not call IoSetFileOrigin.
