- Description
The SetCooperativeLevel() method will establish this device instance's cooperative level.
Acquiring the system mouse in exclusive mode will cause the mouse pointer to disappear until the device is unaquired.
You will need to call this method before calling TDx_InputDevice::Acquire().
Error Values that can be generated are:
DIERR_INVALIDPARAM
DIERR_NOTINITIALIZED
- Parameters
HWnd
The HWnd parameter defines the window handle being associated with the device.
This is a valid top level window handle belonging to this process.
The associated window must not be destroyed while the device is still active.
Flags
The Flags parameter defines flags indicating the cooperative level being set for the device.
The described effect applies when the flag is set.

DISCL_BACKGROUND
Background access is required.
The device may be acquired anytime, even when its associated window is not active.
This flag or DISCL_FOREGROUND must be set, but not both.

Exclusive access is required.
No other device instance can gain exclusive access while the device is acquired.
This flag or DISCL_NONEXCLUSIVE must be set, but not both.

Multiple applications can access the device without interference.
This flag or DISCL_EXCLUSIVE must be set, but not both.
