Hi,

Imho, EACCESS is indeed a bit misleading because it suggests permission
problems. Better would be to have an EFAIL as a generic error. Actually i
was missing an EFAIL several times when my programs needed to return
an error code that did not match well with what i found in errno.h .

I had a quick poke into sys/errno.h and there i found 5 error codes
beginning with ELIB. One of those should suffice. My fafourite is this:

    #define ELIBBAD 84.     /* Accessing a corrupted shared lib */

Because side-by-side problems may mean that the supporting DLL is
acutally there and can be read (also for execute), but the accompanying
XML file describes it incorrectly (e.g. wrong version number), the DLL
is not signed correctly, is not placed in the subdirectory whose name
is mandated by Windows, etc.

There is no need for the 'no', i'd suggest ELIBBAD.

(And to bring back to memory, i'd also suggest to add EFAIL be added)

P.S.: thanks for the hint, Pawel.
