Enumerating Volume GUID Paths

The code example in this topic shows you how to obtain a volume GUID path for each local volume associated with a drive letter that is currently in use on the computer.

The code example uses the GetVolumeNameForVolumeMountPoint function.

#include <windows.h>
#include <stdio.h>
#include <tchar.h>

#define BUFSIZE MAX_PATH 

void main(void)
 {
 BOOL bFlag;
 TCHAR Buf[BUFSIZE]; // temporary buffer for volume name
 TCHAR Drive[] = TEXT("c:\\"); // template drive specifier
 TCHAR I; // generic loop counter

 // Walk through legal drive letters, skipping floppies.
 for (I = TEXT('c'); I < TEXT('z'); I++ ) 
 {
 // Stamp the drive for the appropriate letter.
 Drive[0] = I;

 bFlag = GetVolumeNameForVolumeMountPoint(
 Drive, // input volume mount point or directory
 Buf, // output volume name buffer
 BUFSIZE ); // size of volume name buffer

 if (bFlag) 
 {
 _tprintf (TEXT("The ID of drive \"%s\" is \"%s\"\n"), Drive, Buf);
 }
 }
 }

For an example that enumerates all locally attached volumes and displays the device path, volume GUID path, and mounted paths (including drive letters), see Displaying Volume Paths.
