[erlang-questions] use of disksup

[simone8280@REDACTED]

Hi! I'm new in eralng programming; I want to write a small application for know 
the size of a disk and its available space, in Windows environment. I found the 
module disksup (function get_disk_data()). I try to use it but without success, 
I'm not able to configure it (it need a configuration with module os_mon). Can 
you help me? I need to configure get_disk_data() function and to specify the 
disk I want to analyze (for example I want to know the space's amount of drive 
a:). If you write a few line of source of exemple I'm very happy. (well there 
are an infinity of way to know the size of a disk but I want to do it with 
erlang)     

  thankyou, see you at next
