One way initialization

[shauleiz]

v2.1.7

Kernel:

The device initialize its position when starting.
The Initialization follows an algorithm that includes reading from the registry and falling back to hard-coded values.

User Mode:

When a device entry is created (vJoyDeviceEntry()) the code initializes the device following the same algorithm.

Drawbacks:

• Duplicate logic
• When starting a feeder it initializes the device entry to default while the "physical" device may be in another position that was set previously.

Enhancement

No changes in the initialization of the kernel
Initialization of the user mode will be done by reading the kernel current position.

Code:

• Add IOCTL that reads the device position from the kernel
• Add handle to the IOCTL in the kernel and change initialization code in the API code
