Function Documentation

VirtioFsFuseStatFs()

EFI_STATUS VirtioFsFuseStatFs	(	IN OUT VIRTIO_FS *	VirtioFs,
		IN UINT64	NodeId,
		OUT VIRTIO_FS_FUSE_STATFS_RESPONSE *	FilesysAttr
	)

Send the FUSE_STATFS request to the Virtio Filesysem device, for retrieving the attributes of the host-side filesystem that contains NodeId.

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_STATFS request to. On output, the FUSE request counter "VirtioFs->RequestId" will have been incremented.
[in]	NodeId	The inode whose containing filesystem is to be queried for its attributes.
[out]	FilesysAttr	The VIRTIO_FS_FUSE_STATFS_RESPONSE object describing the filesystem that underlies NodeId.

Return values

EFI_SUCCESS

FilesysAttr 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().
