Function Documentation

VirtioFsFuseFlush()

EFI_STATUS VirtioFsFuseFlush	(	IN OUT VIRTIO_FS *	VirtioFs,
		IN UINT64	NodeId,
		IN UINT64	FuseHandle
	)

Flush changes queued on the local virtualization host to the remote storage server's memory (not storage device), over the network, by sending the FUSE_FLUSH 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_FLUSH request to. On output, the FUSE request counter "VirtioFs->RequestId" will have been incremented.
[in]	NodeId	The inode number of the regular file to flush.
[in]	FuseHandle	The open handle to the regular file to flush.

Return values

EFI_SUCCESS

The regular file has been flushed.

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().
