This 41 * is an interface between input devices and their clients. The interface 42 * defines an idealized user input device that may not correspond to any 43 * existing physical collection of input devices. 44 * 45 * It is targeted to input devices that gather command data from humans, 46 * e.g., mice, keyboards, tablets, joysticks, light pens, knobs, sliders, 47 * buttons, ascii terminals, etc. The vuid interface is specifically not 48 * designed to support input devices that produce voluminous amounts of 49 * data, e.g., input scanners, disk drives, voice packets. 50 * 51 * Here are some of the properties that are expected of a typical client 52 * of vuid: 53 * 54 * The client has a richer user interface than can be supported by 55 * a simple ascii terminal. 56 * 57 * The client serializes multiple input devices being used 58 * by the user into a single stream of events. 59 * 60 * The client preserves the entire state of its input so that 61 * it may query this state. 62 * 63 * Here are some features that vuid provides to its clients: 64 * 65 * A client may extend the capabilities of the predefined vuid by 66 * adding input devices. A client wants to be able to do this in 67 * a way that fits smoothly with its existing input paradigm. 68 * 69 * A client can write its code to be input device independent. A 70 * client can replace the underlaying physical devices and not 71 * have to be concerned. In fact, the vuid interface doesn't 72 * really care about physical devices. One physical device can 73 * masquerade a many logical devices and many physical devices can 74 * look like a single logical device. 75 * 76 * This file defines the protocol that makes up the virtual user input 77 * device. This includes: 78 * 79 * The vuid station codes and there meanings. 80 * 81 * The form by which changes to vuid stations, i.e., firm events, 82 * are communicated to clients (typically via the read system 83 * call). 84 * 85 * The form by which clients send commands to input devices that 86 * support the vuid (typically via an ioctl system call to send 87 * vuid instead of a native byte stream). 88 * 89 * Explicitly, this file does not define: 90 * 91 * How to store the state of the vuid 92 * (see ../sunwindowdev/vuid_state.h). 93 * 94 * How to dynamically allocate additional vuid segments in order 95 * to extend the vuid (one could statically allocate additional 96 * vuid segments by treating this file as the central registry 97 * of vuid segments). 98 */ 99 100 /* 101 * VUID_SEG_SIZE is the size of a virtual user input "device" address space 102 * segment. 103 */ 104 #define VUID_SEG_SIZE (256) 105 106 /* 107 * This is the central registry of virtual user input devices. 108 * To allocate a new vuid: 109 * 110 * o Choose an unused portion of the address space. 111 * Vuids from 0x00 to 0x7F are reserved for Sun implementers. 112 * Vuids from 0x80 to 0xFF are reserved for Sun customers. 113 * 114 * o Note the new device with a *_DEVID define.
