A \fIBadMatch\fP error will be generated if the +requested device does not support feedbacks. Whether or not a given +device supports feedbacks can be determined by examining the information +returned by the \fIXOpenDevice\fP request. For those devices that +support feedbacks, \fIXOpenDevice\fP will return an +\fIXInputClassInfo\fP structure with the input_class field +equal to the constant \fIFeedbackClass\fP (defined in the file \fIXI.h\fP). +.LP +The \fIXGetFeedbackControl\fP request returns a pointer to a list of +\fIXFeedbackState\fP structures. Each item in this list describes one +of the feedbacks supported by the device. The items are variable length, +so each contains its length to allow traversal to the next item in the +list. +.LP +The feedback classes that are currently defined are: \fIKbdFeedbackClass\fP, +\fIPtrFeedbackClass\fP, \fIStringFeedbackClass\fP, \fIIntegerFeedbackClass\fP, +\fILedFeedbackClass\fP, and \fIBellFeedbackClass\fP. These constants are +defined in the file \fIXI.h\fP. An input device may +support zero or more classes of feedback, and may support multiple feedbacks +of the same class. Each feedback contains a class identifier and an id +that is unique within that class for that input device. The id is used +to identify the feedback when making an \fIXChangeFeedbackControl\fP request. +.LP +\fIXGetFeedbackControl\fP can generate a \fIBadDevice\fP or +\fIBadMatch\fP error. +.LP +The \fIXChangeFeedbackControl\fP request modifies the values of one +feedback on the specified device. The feedback is identified by the id +field of the \fIXFeedbackControl\fP structure that is passed with the +request. The fields of the feedback that are to be modified are identified +by the bits of the mask that is passed with the request. +.LP +\fIXChangeFeedbackControl\fP can generate a \fIBadDevice\fP, +\fIBadMatch\fP, or \fIBadValue\fP error. +.SH STRUCTURES +Each class of feedback is described by a structure specific to that class. +These structures are defined in the file \fIXInput.h\fP. +\fIXFeedbackState\fP and \fIXFeedbackControl\fP are generic +structures that contain three fields that are at the beginning of each class +of feedback: +.LP +.DS +typedef struct { +.br + XID class; +.br + int length; +.br + XID id; +.br +} XFeedbackState, XFeedbackControl; +.DE +.LP +The \fIXKbdFeedbackState\fP structure defines the attributes that are +returned for feedbacks equivalent to those on the X keyboard. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int click; + int percent; + int pitch; + int duration; + int led_mask; + int global_auto_repeat; + char auto_repeats[32]; +} XKbdFeedbackState; +.fi +.DE +.LP +The \fIXPtrFeedbackState\fP structure defines the attributes that are +returned for feedbacks equivalent to those on the the X pointer. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int accelNum; + int accelDenom; + int threshold; +} XPtrFeedbackState; +.fi +.DE +.LP +The \fIXIntegerFeedbackState\fP structure defines attributes that are +returned for integer feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int resolution; + int minVal; + int maxVal; +} XIntegerFeedbackState; +.fi +.DE +.LP +The \fIXStringFeedbackState\fP structure defines the attributes that are +returned for string feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int max_symbols; + int num_syms_supported; + KeySym *syms_supported; +} XStringFeedbackState; +.fi +.DE +.LP +The \fIXBellFeedbackState\fP structure defines the attributes that are +returned for bell feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int percent; + int pitch; + int duration; +} XBellFeedbackState; +.fi +.DE +.LP +The \fIXLedFeedbackState\fP structure defines the attributes that are +returned for LED feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int led_values; +} XLedFeedbackState; +.fi +.DE +.LP +The \fIXPrtFeedbackControl\fP structure defines the attributes that can be +controlled for pointer feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int accelNum; + int accelDenom; + int threshold; +} XPtrFeedbackControl; +.fi +.DE +.LP +The \fIXKbdFeedbackControl\fP structure defines the attributes that can be +controlled for keyboard feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int click; + int percent; + int pitch; + int duration; + int led_mask; + int led_value; + int key; + int auto_repeat_mode; +} XKbdFeedbackControl; +.fi +.DE +.LP +The \fIXStringFeedbackControl\fP structure defines the attributes that can be +controlled for string feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int num_keysyms; + KeySym *syms_to_display; +} XStringFeedbackControl; +.fi +.DE +.LP +The \fIXIntegerFeedbackControl\fP structure defines the attributes that can +be controlled for integer feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int int_to_display; +} XIntegerFeedbackControl; +.fi +.DE +.LP +The \fIXBellFeedbackControl\fP structure defines the attributes that can be +controlled for bell feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int percent; + int pitch; + int duration; +} XBellFeedbackControl; +.fi +.DE +.LP +The \fIXLedFeedbackControl\fP structure defines the attributes that can be +controlled for LED feedbacks. +.LP +.DS +.nf +typedef struct { + XID class; + int length; + XID id; + int led_mask; + int led_values; +} XLedFeedbackControl; +.fi +.DE +.SH DIAGNOSTICS +.TP 12 +\fIBadDevice\fP +An invalid device was specified.
