The GetLogicalDriveStrings function fills a buffer with strings that specify valid drives in the system.
DWORD GetLogicalDriveStrings(
DWORD nBufferLength, |
// size of buffer |
LPTSTR lpBuffer |
// address of buffer for drive strings |
); |
c:\<null>d:\<null><null>
If the function succeeds, the return value is the length, in characters, of the strings copied to the buffer, not including the terminating null character. Note that an ANSI-ASCII null character uses one byte, but a Unicode null character uses two bytes.
If the buffer is not large enough, the return value is greater than nBufferLength. It is the size of the buffer required to hold the drive strings.
If the function fails, the return value is zero. To get extended error information, use the GetLastError function.
Each string in the buffer may be used wherever a root directory is required, such as for the GetDriveType and GetDiskFreeSpace functions.
GetDriveType, GetDiskFreeSpace, GetLogicalDrives
