mkstemp(3) creates temporary files with permissions 0600. That's what
the manual page says.
However, a user with a 777 umask (or 600) will get his temp files
created with permissions 000.
Vi (the editor) is having trouble with that as it expects the file to
be read/writable. OpenBSD have ``fixed'' vi to fchmod 0600 the file.
The question for this list is:
- is it acceptable to have mkstemp(3) ensure that the created file is
0600 (as the manual page claims somehow)?
- otherwise, could we point users to the fact that mkstemp, using
open(2), is subject to umask(2) behaviour?
As for vi, I intend to fail properly if the temp file is not
read/writable. People with such umask's wouldn't want to run vi. ;-)
