digitalmars.D.learn - listRoots?

Hi

At first sight I can't find a way to get all the partitions on the user his 
system.
I'm looking for something like File.listRoots() in Java.
Anyone knows a way to do this?

Thanks

Does this do what you want (see attached).  Output on my system is:

HDD: [C:\,D:\,G:\]
FDD: [A:\]
CDD: [E:\]

 Just realised I could template it and easily support all types.  Attached 
 is a new one.

 import std.stdio, std.string;

 alias std.string.toStringz CSTR;

 import std.c.windows.windows;

 extern(Windows)
 {
 DWORD GetLogicalDrives();
 UINT GetDriveTypeA(LPCSTR lpRootPathName);
 UINT GetDriveTypeW(LPCWSTR lpRootPathName);
 const UINT DRIVE_UNKNOWN     = 0; //The drive type cannot be determined.
 const UINT DRIVE_NO_ROOT_DIR = 1; //The root path is invalid; for example, 
 there is no volume is mounted at the path.
 const UINT DRIVE_REMOVABLE   = 2; //The drive has removable media; for 
 example, a floppy drive, thumb drive, or flash card reader.
 const UINT DRIVE_FIXED       = 3; //The drive has fixed media; for 
 example, a hard drive or flash drive.
 const UINT DRIVE_REMOTE      = 4; //The drive is a remote (network) drive.
 const UINT DRIVE_CDROM       = 5; //The drive is a CD-ROM drive.
 const UINT DRIVE_RAMDISK     = 6; //The drive is a RAM disk.
 }

 char[][] LocalDrives()
 {
 DWORD mask = GetLogicalDrives();
 char[] drive = new char[3];
 char[][] list;

 drive[1..3] = ":\\";
 for(int i = 0; i < 26; i++)
 {
 if (mask & 0x1<<i)
 {
 drive[0] = 'A'+i;
 list ~= drive.dup;
 }
 }

 return list;
 }

 template SortDrive(UINT TYPE) { char[][] SortDrive() {
 char[][] list;

 foreach(drive; LocalDrives())
 {
 switch(GetDriveTypeA(CSTR(drive)))
 {
 case TYPE:
 list ~= drive;
 break;
 default:
 break;
 }
 }

 return list;
 }}

 alias SortDrive!(DRIVE_FIXED) FixedDrives;
 alias SortDrive!(DRIVE_REMOVABLE) RemovableDrives;
 alias SortDrive!(DRIVE_REMOTE) RemoteDrives;
 alias SortDrive!(DRIVE_CDROM) CdDrives;
 alias SortDrive!(DRIVE_RAMDISK) RamDisks;

 void main()
 {
 writef("Fixed    : ",FixedDrives(),"\n");
 writef("Removable: ",RemovableDrives(),"\n");
 writef("Remote   : ",RemoteDrives(),"\n");
 writef("Cd       : ",CdDrives(),"\n");
 writef("Ramdisk  : ",RamDisks(),"\n");
 }


That does the trick. Thanks a lot!

This works without fault on my XP SP2 system.

I should also state "This code is public domain".  That is, all code I posted
in this the "listRoots?" thread is public domain.

p.s. Of course mentioning my name in your code comments or wherever would make
me happy ;)

Would you loke to add this to scrapple?

For some reason that link isn't working for me.

I assume it's a library of sorts?

Assuming there is no problem with the fact that I made my code public domain
feel free to add the code I posted to scrapple.  I'd appreciate a mention
somewhere even if it's just in a comment by the code itself.

It looks like dsource is down (though I can still ping it).

Of sorts. It's basically an "miscellaneous" project, containing useful 
stuff that for one reason or another isn't hosted elsewhere.

Speaking of which, I would love it if there were some place where one 
could browse for all known D projects, with a keyword index.  Probably 
Dsource is the closest thing to a clearing house for D code, but some 
people just want to host their own stuff.

Anyway, I'm thinking of a PyPI (Python Package Index) type thing.  You 
don't have to host your project on PyPI, though you can, but whether you 
do or not, you can register your project, supply keywords, and a brief 
description and a pointer to where the code can be found.

I was thinking DSSS was going to sprout something like that, but as far 
as I know, DSSS finds -net packages via some less public route.
