2376 | If Value for the false possibility is greater at compile time(retval == - ECHILD) Then retval = Returns 0 and nd will be valid on success; Retuns error, otherwise. |
2378 | If Value for the false possibility is greater at compile time(retval == - ESTALE) Then retval = Returns 0 and nd will be valid on success; Retuns error, otherwise. |
2380 | If Value is more likely to compile time(!retval) Then |
