Here's what I do in libsndfile:
- Errors are integers from 0 (SFE_NO_ERROR) through to some
maximum error number (which can change from release to
release).
- API functions can return an error number.
- The API supplies a function (rather than a string array)
to convert the error number into a "const char *" string
after checking that the error number is in the valid range.
- Using a function means that error messages can be added and
removed from release to release without breaking the API.
Hope this helps,
Erik
