Function Documentation

VirtioFsFuseRename()

EFI_STATUS VirtioFsFuseRename	(	IN OUT VIRTIO_FS *	VirtioFs,
		IN UINT64	OldParentNodeId,
		IN CHAR8 *	OldName,
		IN UINT64	NewParentNodeId,
		IN CHAR8 *	NewName
	)

Rename a regular file or a directory, by sending the FUSE_RENAME2 request to the Virtio Filesystem device. If the new filename exists, the request will fail.

The function may only be called after VirtioFsFuseInitSession() returns successfully and before VirtioFsUninit() is called.

Parameters

[in,out]	VirtioFs	The Virtio Filesystem device to send the FUSE_RENAME2 request to. On output, the FUSE request counter "VirtioFs->RequestId" will have been incremented.
[in]	OldParentNodeId	The inode number of the directory in which OldName should be removed.
[in]	OldName	The single-component filename to remove in the directory identified by OldParentNodeId.
[in]	NewParentNodeId	The inode number of the directory in which NewName should be created, such that on successful return, (NewParentNodeId, NewName) refer to the same inode as (OldParentNodeId, OldName) did on entry.
[in]	NewName	The single-component filename to create in the directory identified by NewParentNodeId.

Return values

EFI_SUCCESS

The file or directory has been renamed.

Returns

The "errno" value mapped to an EFI_STATUS code, if the Virtio Filesystem device explicitly reported an error.

Error codes propagated from VirtioFsSgListsValidate(), VirtioFsFuseNewRequest(), VirtioFsSgListsSubmit(), VirtioFsFuseCheckResponse().
