DESCRIPTION	Name____
points to a null-terminated string.
Unlink______
removes the entry for the file pointed to by name____
from its directory.
If this entry was the last link to the file,
the contents of the file are freed and the file is destroyed.
If, however, the file was open in any process, the actual
destruction is delayed until it is closed, even though
the directory entry has disappeared.
