/dev/screen subdirectory

What is /dev/screen subdirectory for ?

In my box, the permissions of this subdir are 777... As this subdir resides in root file system, anyone can fill up the root filesystem.

Re: /dev/screen subdirectory

/dev/screen was used primarily by a program called xwcreate and starbase back in the 90s.

I'm not sure what it is currently used for.

Actually, its still around today.

On 11.x, it lives in:

/opt/graphics/common/bin/xwcreate

xwcreate creates device files for local and
remote displays,used by Starbase applications.
I found this (for 8.x and 9.x !) security

Anyway,777 isn't a lucky number in the Unix world :)/dev should not contain world-writable
files.
