VirtioFsFuseGetAttr()

EFI_STATUS VirtioFsFuseGetAttr	(	IN OUT VIRTIO_FS *	VirtioFs,
		IN UINT64	NodeId,
		OUT VIRTIO_FS_FUSE_ATTRIBUTES_RESPONSE *	FuseAttr
	)

Send a FUSE_GETATTR request to the Virtio Filesystem device, for fetching the attributes of an inode.

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_GETATTR request to. On output, the FUSE request counter "VirtioFs->RequestId" will have been incremented.
[in]	NodeId	The inode number for which the attributes should be retrieved.
[out]	FuseAttr	The VIRTIO_FS_FUSE_ATTRIBUTES_RESPONSE object describing the properties of the inode.

Return values

EFI_SUCCESS

FuseAttr has been filled in.

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().
