Alternative Managed API:

Do you know one? Please contribute it!


Code is tested on Windows Embedded Standard 7 32bit.

Tips & Tricks:

The "volumeList" parameter is a pointer to a multi-wide-string meaning one character consists of 2 bytes, every string is terminated by 2 NUL bytes and the whole thing is terminated by 4 NUL bytes.

Using a custom marshaler for this type might be possible as it is used a couple of times in this API.

Sample Code:

uint size = 100;
var pBuffer = Marshal.AllocHGlobal((int)size);
NativeMethods.FbwfGetVolumeList(true, pBuffer, ref size);
//TODO convert pbuffer to strings
