Sure there is.  For example, as recently discussed on this newsgroup,
the ANSI C standard provides a function rename() for renaming files,
but not all systems have that capability.  A conforming implementation
can indicate that it doesn't support that feature by defining rename()
to always return -1 and setting errno to some appropriate value such
as ENOSYS.
