Hello,
Yesterday, I sent this message to have a little help of lua friends ..
------------------------
Hello,
I need to retrieve HDD's infos in lua, and store them in variables.
Does someone has an idea, especially the physical serial number, not the
one after formatting ?
Thanks,
JM Venet
-------------------
today, after hard searching on the net, I found this : For windows, the
disk informations are retrieveable via the library kernell32.dll with
the function GetVolumeInformation this function sends these datas
(contained in a data structure:
_In_opt_ LPCTSTR lpRootPathName,
_Out_opt_ LPTSTR lpVolumeNameBuffer,
_In_ DWORD nVolumeNameSize,
_Out_opt_ LPDWORD lpVolumeSerialNumber,
_Out_opt_ LPDWORD lpMaximumComponentLength,
_Out_opt_ LPDWORD lpFileSystemFlags,
_Out_opt_ LPTSTR lpFileSystemNameBuffer,
_In_ DWORD nFileSystemNameSize
I coded with Wscite this :
local path = 'C:\\Windows\\System32\\kernell32.dll'
local func = package.loadlib(path, 'GetVolumeInformation')
a = {}
a[1] = func.lpRootPathName
a[2] = func.lpVolumeNameBuffer
a[3] = func.nVolumeNameSize
a[4] = func.lpVolumeSerialNumber
a[5] = func.lpMaximumComponentLength
a[6] = func.lpFileSystemFlags
a[7] = func.lpFileSystemNameBuffer
a[8] = func.nFileSystemNameSize
after process by F5, I received the following messages
>lua -e "io.stdout:setvbuf 'no'" "test.lua"
lua: test.lua:6: attempt to index local 'func' (a nil value)
stack traceback:
test.lua:6: in main chunk
[C]: ?
>Exit code: 1
If I put the lines from the statement a = {}, to the end in comments the
messages are : (func is nil)
lua -e "io.stdout:setvbuf 'no'" "test.lua"
>Exit code: 0
is there someone who can give me a little help to retrieve the datas
contained in the stucture returned by the function GetVolumeInformation
thanks for help JM Venet
