Interpretation Request #59
Topic: readdir_r errors Relevant Sections: XSH readdir_r Page: 1198 Line: 37516-37523

The errors section for readdir() and readdir_r() has a shall fail EOVERFLOW error for readdir(), but not for readdir_r(). The same condition applies to both functions and should be a shall fail error for both functions.

Similarly, EBADF and ENOENT are listed as may fail errors for readdir(), but only EBADF is listed as a may fail error for readdir_r(). The ENOENT condition should apply to both functions.

Change "readdir() function" on P1198, L37516 to "readdir() and readdir_r() functions".

Change "readdir() function" on P1198, L37519 to "readdir() and readdir_r() functions".

Delete P1198, L37522-37523.

Interpretation Response #59
The standards states the requirements for errors for readdir() and readdir_r(), and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor.
