====== List all available drives ======

<file>This code snippet is originally from the former WinAPI site www.winapi.net</file>

Sometimes you need to know about all logical drives. The WinAPI gives us for that the function ''GetLogicalDrives()''. It returns a bit mask which has to be analysed. Here is an example how:

<code c>#include <windows.h>
#include <tchar.h>
#include <shlwapi.h>
#include <stdio.h>

#ifndef BITSPERBYTE
#define BITSPERBYTE 8
#endif

#define IS_BIT(val, bit) ((val) & (1 << (bit)))

int _tmain(void)
{
   DWORD dwLogicalDrives, x;
   TCHAR szRoot[32];

   dwLogicalDrives = GetLogicalDrives();

   for(x = 0; x < (sizeof(dwLogicalDrives) * BITSPERBYTE); x++)
   {
      if(IS_BIT(dwLogicalDrives, x))
      {
         PathBuildRoot(szRoot, x);
         _tprintf(TEXT("%s - DriveType: 0x%08X\n"), szRoot, GetDriveType(szRoot));
      }
   }
   return(0);
}
