IoIsFileOriginRemote function (ntddk.h)

The IoIsFileOriginRemote routine determines whether a given file object is for a remote create request.

Syntax

BOOLEAN IoIsFileOriginRemote(
  [in] PFILE_OBJECT FileObject
);

Parameters

[in] FileObject

Pointer to a file object for the file.

Return value

IoIsFileOriginRemote returns TRUE if the file object was created to satisfy a remote create request, otherwise FALSE.

Remarks

File system filter drivers call IoIsFileOriginRemote for a file object to determine whether it represents a remote create request.

IoIsFileOriginRemote must be called after the create request has entirely completed. In other words, it cannot be called in the create dispatch ("pre-create") path or the create completion ("post-create") path.

IoIsFileOriginRemote checks the FO_REMOTE_ORIGIN flag on the file object pointed to by FileObject. Network file systems set or clear this flag by calling IoSetFileOrigin.
