| Summary | 0000572: dirfd() ENOTSUP can never happen | ||||||
| Description |
The dirfd() page includes this optional error: [ENOTSUP] The implementation does not support the association of a file descriptor with a directory. However, if open() is called with the pathname of a directory and with the flag O_SEARCH, the standard requires it to return a file descriptor that refers to the directory; therefore no conforming implementation could ever meet the ENOTSUP condition. Also, I can see no reason why dirfd() should be allowed not to set errno when it returns -1. The proposed changes correct this by changing "may" to "shall" in the RETURN VALUE section. Finally, there is a misspelling of opendir() in the rationale. |
||||||
| Desired Action |
At line 24333 change: and may set errno to: and shall set errno At line 24338 delete the ENOTSUP error. At line 24351 change "diropen()" to "opendir()". At line 24354 delete: An implementation that does not support file descriptors referring to directories may fail with [ENOTSUP]. |

Interpretation response ------------------------ The standard states that implementations need not set errno, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: ------------- All implementations must support a file descriptor referring to a directory, even if that descriptor is not used by readdir(). Furthermore, failure of dirfd() without setting errno is not useful to applications. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- See Desired Action |

Note that the RATIONALE change from diropen() to opendir() has already been done in the 2013 edition and so does not need to be included in TC2. |
