Function Documentation

VirtioFsFuseRemoveFileOrDir()

EFI_STATUS VirtioFsFuseRemoveFileOrDir	(	IN OUT VIRTIO_FS *	VirtioFs,
		IN UINT64	ParentNodeId,
		IN CHAR8 *	Name,
		IN BOOLEAN	IsDir
	)

Remove a regular file or a directory, by sending the FUSE_UNLINK or FUSE_RMDIR 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_UNLINK / FUSE_RMDIR request to. On output, the FUSE request counter "VirtioFs->RequestId" will have been incremented.
[in]	ParentNodeId	The inode number of the directory in which Name should be removed.
[in]	Name	The single-component filename to remove in the directory identified by ParentNodeId.
[in]	IsDir	TRUE if Name refers to a directory, FALSE otherwise.

Return values

EFI_SUCCESS

The file or directory has been removed.

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().
