EFI_STATUS VirtioFsFuseOpen	(	IN OUT VIRTIO_FS *	VirtioFs,
		IN UINT64	NodeId,
		IN BOOLEAN	ReadWrite,
		OUT UINT64 *	FuseHandle
	)

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

Parameters

[in]	NodeId	The inode number of the regular file to open.
[in]	ReadWrite	If TRUE, open the regular file in read-write mode. If FALSE, open the regular file in read-only mode.
[out]	FuseHandle	The open handle to the regular file, returned by the Virtio Filesystem device.

Return values

EFI_SUCCESS

The regular file has been opened.

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().
