XF86MISC(3) Library Functions Manual XF86MISC(3) NAME XF86MiscQueryExtension, XF86MiscQueryVersion, XF86MiscGetMouseSettings, XF86MiscSetMouseSettings, XF86MiscGetKbdSettings, XF86MiscSetKbdSet- tings - Extension library for the XFree86-Misc X extension. SYNTAX #include <X11/extensions/xf86misc.h> Bool XF86MiscQueryExtension( Display *display, int *event_base_return, int *error_base_return); Bool XF86MiscQueryVersion( Display *display, int *major_version_return, int *minor_version_return); Status XF86MiscGetMouseSettings( Display *display, XF86MiscMouseSettings *mseinfo); Status XF86MiscSetMouseSettings( Display *display, XF86MiscMouseSettings *mseinfo); Status XF86MiscGetKbdSettings( Display *display, XF86MiscKbdSettings *kbdinfo); Status XF86MiscSetKbdSettings( Display *display, XF86MiscKbdSettings *kbdinfo); ARGUMENTS display Specifies the connection to the X server. screen Specifies which screen number the setting apply to. event_base_return Returns the base event number for the extension. error_base_return Returns the base error number for the extension. major_version_return Returns the major version number of the extension. minor_version_return Returns the minor version number of the extension. mseinfo Specifies a structure which contains the mouse pa- rameters. kbdinfo Specifies a structure which contains the keyboard parameters. STRUCTURES Mouse: typedef struct { char *device; /* returned path to device */ int type; /* mouse protocol */ int baudrate; /* 1200, 2400, 4800, or 9600 */ int samplerate; /* samples per second */ int resolution; /* resolution, count per inch */ int buttons; /* number of buttons */ Bool emulate3buttons; /* Button1+Button3 -> Button2 ? */ int emulate3timeout; /* in milliseconds */ Bool chordmiddle; /* Button1+Button3 == Button2 ? */ int flags; /* Device open flags */ } XF86MiscMouseSettings; Keyboard: typedef struct { int type; /* of keyboard: 84-key, 101-key, Xqueue */ int rate; /* repeat rate */ int delay; /* delay until repeat starts */ Bool servnumlock; /* Server handles NumLock ? */ } XF86MiscKbdSettings; DESCRIPTION These functions provide an interface to the XFree86-Misc extension which allows various server settings to be queried and changed dynami- cally. Applications that use these functions must be linked with -lXxf86misc POWER-SAVER FUNCTIONS The XF86MiscGetSaver and XF86MiscSetSaver functions have been removed. This functionality is now provided by the DPMS extension. MOUSE FUNCTIONS Mouse parameters can be queried using the function XF86MiscGetMouseSet- tings. The structure pointed to by its second argument is filled in with the current mouse settings. Not all fields are valid in all cases. For example, when the protocol indicates a bus mouse (i.e. the type field has value MTYPE_BUSMOUSE as defined in xf86misc.h), then the value in the baudrate field should be ignored as it does not apply to bus mice. The samplerate field contains the resolution in lines per inch when us- ing the Hitachi tablet protocol. The device field of the structure points to dynamically allocated stor- age which should be freed by the caller. Any of the fields of the structure can be altered and then passed to the XF86MiscSetMouseSettings function to change their value in the server, with the following restrictions: 1) The device can not be changed 2) The protocol can not be changed to or from Xqueue or OsMouse 3) The buttons field can not be changed 4) Invalid combinations of parameters are not allowed The server will generate an error if any of the above is attempted, ex- cept the first - the contents of the device field are simply ignored. A change of the protocol causes the device to be closed and reopened. Changes to the baud rate, sample rate, resolution or flags, when ap- plicable to the selected protocol, also cause a reopen of the device. A reopen can be forced by using the MF_REOPEN flag, except in the case of the OsMouse and Xqueue protocols which ignore all attempts to reopen the device. KEYBOARD FUNCTIONS The XF86MiscGetKbdSettings function allows you to retrieve the current keyboard-related settings from the server. Using the XF86MiscSetKbdSettings function, the keyboard autorepeat de- lay and rate can be set. Requests to change the type and servnumlock fields are ignored (except for checking for an invalid keyboard type). This is expected to change in a future release. OTHER FUNCTIONS Two functions, XF86MiscQueryExtension and XF86MiscQueryVersion, are provided which allow the client to query some information regarding the extension itself. PREDEFINED VALUES The header file X11/extensions/xf86misc.h contains definitions for MTYPE_* Mouse protocols KTYPE_* Keyboard types MF_* Mouse flags SEE ALSO xset(1), xorg.conf(5) AUTHORS Joe Moss and David Dawes, The XFree86 Project, Inc.
