SockPathMode - what is it? I have a plist installed on my system with the following in it:

&lt;dict&gt;
  &lt;key&gt;SockPathMode&lt;/key&gt;
  &lt;integer&gt;438&lt;/integer&gt;


man launchd.plist tells me:

SockPathMode &lt;integer&gt;
This optional key specifies the mode of the socket.


I haven't been able to find a list of modes and I haven't heard of 438 different modes either! If anyone can shed some light on what this key and value is really about I'd be very grateful.
The integer in the key SockPathMode is the decimal presentation of the octal POSIX permissions of the UNIX socket.

Converter: 438 > 0666 > file permissions: rw-rw-rw- (owner, group and anyone is allowed to read and write from/to the socket.
