XkbGetUpdatedMap(3) XKB FUNCTIONS XkbGetUpdatedMap(3) NAME XkbGetUpdatedMap - Update the client or server map information in an existing keyboard description SYNOPSIS Status XkbGetUpdatedMap (Display *display, unsigned int which, XkbDe- scPtr xkb); ARGUMENTS display connection to X server which mask selecting subcomponents to populate xkb keyboard description to be updated DESCRIPTION The which parameter is a bitwise inclusive OR of the masks in Table 1. If the needed components of the xkb structure are not already allo- cated, XkbGetUpdatedMap allocates them. XkbGetUpdatedMap fetches the requested information for the device specified in the XkbDescRec passed in the xkb parameter.

If successful, XkbGe- tUpdatedMap returns Success. If unsuccessful, XkbGetUpdatedMap returns one of the following: BadAlloc (unable to allocate a component in the XkbDescRec structure), BadValue (some mask bits in which are unde- fined), BadImplementation (a compatible version of the Xkb extension is not available in the server or the reply from the server was invalid). RETURN VALUES Success The XkbGetUpdatedMap function returns Success if a reply is received to the server query for the desired informa- tion. STRUCTURES The complete description of an Xkb keyboard is given by an XkbDescRec. The component structures in the XkbDescRec represent the major Xkb com- ponents. typedef struct { struct _XDisplay * display; /* connection to X server */ unsigned short flags; /* private to Xkb, do not modify */ unsigned short device_spec; /* device of interest */ KeyCode min_key_code; /* minimum keycode for device */ KeyCode max_key_code; /* maximum keycode for device */ XkbControlsPtr ctrls; /* controls */ XkbServerMapPtr server; /* server keymap */ XkbClientMapPtr map; /* client keymap */ XkbIndicatorPtr indicators; /* indicator map */ XkbNamesPtr names; /* names for all components */ XkbCompatMapPtr compat; /* compatibility map */ XkbGeometryPtr geom; /* physical geometry of keyboard */ } XkbDescRec, *XkbDescPtr; The display field points to an X display structure. The flags field is private to the library: modifying flags may yield unpredictable re- sults. The device_spec field specifies the device identifier of the keyboard input device, or XkbUseCoreKeyboard, which specifies the core keyboard device. The min_key_code and max_key_code fields specify the least and greatest keycode that can be returned by the keyboard. Each structure component has a corresponding mask bit that is used in function calls to indicate that the structure should be manipulated in some manner, such as allocating it or freeing it. These masks and their relationships to the fields in the XkbDescRec are shown in Table 2.
