84 These functions provide an interface to the XFree86-Misc extension
85 which allows various server settings to be queried and changed dynami‐
86 cally. Applications that use these functions must be linked with
87 -lXxf86misc
88 POWER-SAVER FUNCTIONS
90 The XF86MiscGetSaver and XF86MiscSetSaver functions have been removed.
91 This functionality is now provided by the DPMS extension.
92 MOUSE FUNCTIONS
94 Mouse parameters can be queried using the function XF86MiscGetMouseSet‐
95 tings. The structure pointed to by its second argument is filled in
96 with the current mouse settings.
97 Not all fields are valid in all cases. For example, when the protocol
99 indicates a bus mouse (i.e. the type field has value MTYPE_BUSMOUSE as
100 defined in xf86misc.h), then the value in the baudrate field should be
101 ignored as it does not apply to bus mice.
102 The samplerate field contains the resolution in lines per inch when
104 using the Hitachi tablet protocol.
105 The device field of the structure points to dynamically allocated stor‐
107 age which should be freed by the caller.
108 Any of the fields of the structure can be altered and then passed to
110 the XF86MiscSetMouseSettings function to change their value in the
111 server, with the following restrictions:
112 1) The device can not be changed
114 2) The protocol can not be changed to or from Xqueue or OsMouse
116 3) The buttons field can not be changed
118 4) Invalid combinations of parameters are not allowed
120 The server will generate an error if any of the above is attempted,
122 except the first - the contents of the device field are simply ignored.
123 A change of the protocol causes the device to be closed and reopened.
125 Changes to the baud rate, sample rate, resolution or flags, when appli‐
126 cable to the selected protocol, also cause a reopen of the device. A
127 reopen can be forced by using the MF_REOPEN flag, except in the case of
128 the OsMouse and Xqueue protocols which ignore all attempts to reopen
129 the device.
130 KEYBOARD FUNCTIONS
132 The XF86MiscGetKbdSettings function allows you to retrieve the current
133 keyboard-related settings from the server.
134 Using the XF86MiscSetKbdSettings function, the keyboard autorepeat
136 delay and rate can be set. Requests to change the type and servnumlock
137 fields are ignored (except for checking for an invalid keyboard type).
138 This is expected to change in a future release.
139 OTHER FUNCTIONS
141 Two functions, XF86MiscQueryExtension and XF86MiscQueryVersion, are
142 provided which allow the client to query some information regarding the
143 extension itself.
144
146 The header file X11/extensions/xf86misc.h contains definitions for
147 MTYPE_* Mouse protocols
149 KTYPE_* Keyboard types
151 MF_* Mouse flags
