[erlang-questions] use of disksup

[Kenneth Lundin]

Hi,

The disksup module belongs to the os_mon application which in turn is
dependent on the sasl application.
Therefore you need to start these applications before you call
disksup:get_disk_data().

Like this (in the Erlang shell)

1> application:start(sasl).
ok
2> application:start(os_mon).
ok
3> disksup:get_disk_data().
[{"C:\\",200047001600,69},{"G:\\",39991275520,35}]
4>

The above result was what I got on my Windows XP machine.

It means that C: has a total space of 200047001600 bytes and 69% is
occupied, G: has 39991275520 bytes and 35% is occupied.
While writing this I noticed that the documentation says that the unit
should be Kbytes but it is not in this case. I have to check
if there is a documentation error or if it is a different behaviour on
Windows than on Linux.
I think the use of disksup on Windows is very sparse compared to Linux
and Solaris and that might be the reason for not detecting this
before, if it is bytes only on Windows.
