New Revision: 203990
URL: http://svn.freebsd.org/changeset/base/203990
Log:
Mention EISDIR as a possible errno.
Modified:
head/lib/libc/sys/unlink.2
This is wrong as per POSIX
(<http://www.opengroup.org/onlinepubs/000095399/functions/unlink.html>):
[EPERM]
The file named by path is a directory, and either the calling process
does not have appropriate privileges, or the implementation prohibits
using unlink() on directories.
On a not-entirely-unrelated note, I wonder if
any of the POSIX experts around know whether POSIX
specifies an errno value for this call:
open("/", O_WRONLY | O_EXCL | O_CREAT, 0777)
I ran into this puzzler back when I was trying to optimize
the restore sequence for libarchive. As near as I've
been able to tell, POSIX is ambiguous here: It
requires EISDIR for open(O_WRONLY) on a dir and EEXIST
for open(O_EXCL | O_CREAT) on an existing item but
without any clear guidance on which of those takes
priority in this case.
Anyone think they know the answer?
Cheers,
Tim
