My suggestion was not to propose EFAIL as an error message for a side-by-side error. Not at all. i should have made an extra toipic, actually, and if i would consider it important enough, i would make one now. What i meant was that sometimes i'm writing a program, and when searching for an appropriate error code in errno.h, i don't find one. Then i would prefer to resort to some genereric EFAIL. Imagine a routine decodes an mp3 stream and fails because the mp3 data is corrupt. What error code would match this? The best i found was: #define EBADMSG 77. /* Trying to read unreadable message */ But i guess the solution would be to stay away from these more OS-centric error codes. Again, i do not have a strong desire on discussing EFAIL, so we can stop here.
