Bug ID: 35178
           Summary: FL Studio 11.x 'DirectWave' plugin doesn't work
                    (unsupported FSCTL_IS_VOLUME_MOUNTED ioctl)
           Product: Wine
           Version: 1.7.8
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown

Hello folks,
a user in #winehq reported this.
I was able to reproduce the problem with the demo version of FL 11 using the
following recipe (quoting IRC log):
--- quote ---
<alexmarkley> i am running into an issue with FL Studio 11 running on Linux
under Wine 1.7.8
<alexmarkley> most everything appears to be working, but there are a couple of
important software instrument plugins that fail to load any sounds
...
<alexmarkley> focht: File -> New from template -> Minimal -> Basic with limiter
<alexmarkley> focht: sub-window "Pattern 1", right click "Kick" -> Insert ->
DirectWave
<alexmarkley> focht: in the DirectWave window which appears, click the down
arrow next to "Select Preset"
<alexmarkley> focht: if you don't have any DirectWave presets, you can download
a free one
<alexmarkley> from within the GUI there
<alexmarkley> anyway, once you select the preset you will see it loads the
program, but clicking the piano keys results in no sound
<alexmarkley> focht: you will also notice that, in the loaded program, each
entry in the "Size" column is zero
<alexmarkley> focht: which is bad... in native windows (running in VirtualBox)
i see non-zero values for every one of those entries

--- snip ---
The 'DirectWave' plugin library uses FSCTL_IS_VOLUME_MOUNTED ioctl to check if
the specified volume is mounted before accessing each file (track).
Wine doesn't implement/stub that ioctl hence the failure, resulting in tracks
listed with zero size (as reported).
MSDN:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa364574%28v=vs.85%2...
--- quote ---
FSCTL_IS_VOLUME_MOUNTED control code
Determines whether the specified volume is mounted, or if the specified file or
directory is on a mounted volume.
To perform this operation, call the DeviceIoControl function with the following
parameters.
BOOL DeviceIoControl(
  (HANDLE) hDevice,            // handle to device
  FSCTL_IS_VOLUME_MOUNTED,     // dwIoControlCode
  NULL,                        // lpInBuffer
  0,                           // nInBufferSize
  NULL,                        // lpOutBuffer
  0,                           // nOutBufferSize
  (LPDWORD) lpBytesReturned,   // number of bytes returned
  (LPOVERLAPPED) lpOverlapped  // OVERLAPPED structure
);
...
Return value
If the volume is currently mounted, DeviceIoControl returns a nonzero value.
Otherwise, DeviceIoControl returns zero (0). To get extended error information,
call GetLastError.
Remarks
The NTFS file system treats a locked volume as a dismounted volume. Therefore,
this call returns zero (0) after a volume is locked on the NTFS file system.
--- quote ---
For quick test I short-circuited the ioctl handling on the client side (ntdll)
like the existing FSCTL_LOCK_VOLUME and FSCTL_UNLOCK_VOLUME cases, returning
'success'.
It made the plugin happy and the wav files were correctly loaded/processed.
A more thorough solution is probably enhancing server/mountmgr.
