Function Documentation

VirtioFsFuseReleaseFileOrDir()

EFI_STATUS VirtioFsFuseReleaseFileOrDir	(	IN OUT VIRTIO_FS *	VirtioFs,
		IN UINT64	NodeId,
		IN UINT64	FuseHandle,
		IN BOOLEAN	IsDir
	)

Close a regular file or a directory that is open, by sending the FUSE_RELEASE or FUSE_RELEASEDIR request to the Virtio Filesystem device.

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_RELEASE / FUSE_RELEASEDIR request to. On output, the FUSE request counter "VirtioFs->RequestId" will have been incremented.
[in]	NodeId	The inode number of the file or directory to close.
[in]	FuseHandle	The open handle to the file or directory to close.
[in]	IsDir	TRUE if NodeId and FuseHandle refer to a directory, FALSE if NodeId and FuseHandle refer to a regular file.

Return values

EFI_SUCCESS

The file or directory has been closed.

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().
