I am wondering wether it is possible in emacs to define the UNIX file
creation mode mask. On our Apollo system, emacs creates and saves
files with rw-rw-rw- ignoring the files' original protection rights
and my umask setting.
Do you have some useful hint?
Thanks
Armin

If you'll look in {...}/src/fileio.c, you'll notice a line or two that look something like fd = creat (name, 0666); You could add code that would replace the 0666 with your current umask, and then recompile. --woodstock -- "What I like is when you're looking and thinking and looking and thinking...and suddenly you wake up." - Hobbes nhess@oracle.com or ...!uunet!oracle!nhess or (415) 598-3046

No! If your umask is 22 (a common default) then this would create
files with permissios ----w--w- ... obviously unintended. There
should be a umask function (available as a primitive) which simply
accepts an argument and calls umask(arg). That creat is just fine.
Why there is no umask call is beyond me. (I just scanned the source
directories, no sign of one hidden anywhere. *sigh*)
