Comment (by Jens Schweikhardt):

 If I had to devise a (rough?) guideline:

 1) only pointer parameters are annotated (since scalars are [in] by
 language definition)
 2) [in] indicates that the pointer must point to an initialized object (it
 may be dereferenced by the directive)
 3) [out] indicates that the object pointed to may be written by the
 4) [inout] If both 2) and 3) apply.

 This is basically how I interpret these annotations from the Interface
 Definition Languages from a past life where I used CORBA with a C binding.
 Word-smithing suggestions welcome.
