| Summary | 0000172: getlogin() and fds 0, 1 and 2 | ||||
| Description | Most (possibly all) implementations of getlogin() rely internally on file descriptor 0, 1 or 2 being open to the terminal in order to find it. If all three fds are redirected, for example to plain files or /dev/null, getlogin() fails (with ENOTTY). The standard does not mention this. This also affects the logname utility (via the reference to getlogin() in its description). | ||||
| Desired Action |
At the end of the DESCRIPTION section add a new paragraph:
The getlogin() and getlogin_r() functions may make use of file
descriptors 0, 1 and 2 to find the controlling terminal of the
current process, examining each in turn until the terminal is
found. If none of the three file descriptors is open to the
controlling terminal, the functions may fail. The method
used to find the terminal associated with a file descriptor may
depend on the file descriptor being open to the actual terminal
device, not /dev/tty.
After line 34476 (ENFILE) add:
[ENOTTY] None of the file descriptors 0, 1 or 2 is open to the
controlling terminal of the current process.

Interpretation response ------------------------ The standard is unclear on this issue, and no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor. Rationale: ------------- None. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- The Committee recommends the following changes:
