37 A uniform class to a slot of an HID device.

42 <p class="p1">GeneralHID is a cross platform wrapper for accessing HID devices. Currently the MacOSX and Linux HID support has been wrapped. Some of the code is inspired by the GUI wrapper.</p>
43 <p class="p1">A GeneralHIDSlot accesses one specific capability of a device, such as a button, an axis or an LED. Its value can be retrieved, an action can be set to be performed when data comes in, and the slot can be mapped to a control bus to use the value directly on the server. Slots are automatically created when a device is opened, so it is not necessary for a user to create a new slot.</p>
44 <p class="p2"><br></p>
45 <p class="p1"><b>See </b> <a href="GeneralHID.html"><span class="s2">GeneralHID</span></a> for a complete explanation and an example of how to access an HID device.</p>
47 <p class="p1"><b>It is advised to use this class instead of the platform specific classes:</b> <a href="HIDDeviceService.html"><span class="s2">HIDDeviceService</span> (on MacOSX)</a> and <a href="../Linux/LID.html"><span class="s2">LID</span> (on Linux)</a></p>

50 <p class="p4"><b>Some outstanding issues</b></p>
51 <p class="p2"><br></p>
52 <p class="p1">This class is not completely finished yet. Common slot numbers across platforms are not yet guaranteed. On Windows there is not yet a proper implementation available.
