"The exception Use_Error is propagated if
    -- the external environment does not support the creation of a directory
    -- with the given name (in the absence of Name_Error) and form. "

hi;

Man of the functions in that package raise the above exception.

Does the standard allow the user to obtain a specific error as to why
the exception occured? In practice, one would want to know WHY the error
occured, not just that AN error occured. 

For example, in Unix, one can read the error number to find more information
about why a function failed (returned -1 for example).  Is it possible to
get this info from the detailed of the exception itself here with Ada somehow?
