When another client modifies the compatibility map, you are notified if you have  selected for XkbCompatMapNotify events. XkbGetCompatMap is particularly useful when you receive an event of this type, as it allows you  to update your program's version of the compatibility map to match the modified  version now in the server. If your program is dealing with multiple servers and  needs to configure them all in a similar manner, the updated compatibility map  may be used to reconfigure other servers.

XkbGetCompatMap fetches the components of the compatibility map specified in which from the server specified by display and places them in the compat structure of the keyboard description xkb. Valid values for which are an inclusive OR of the values shown in Table 1.

Table 1 Compatibility Map Component Masks
XkbSymInterpMask(1<<0)Symbol interpretations
XkbGroupCompatMask(1<<1)Group maps
XkbAllCompatMask(0x3)All compatibility map components

If no compatibility map structure is allocated in xkb upon entry, XkbGetCompatMap allocates one. If one already exists, its contents are overwritten with the  returned results.

XkbGetCompatMap fetches compatibility map information for the device specified by the device_spec field of xkb. Unless you have specifically modified this field, it is the default keyboard  device. XkbGetCompatMap returns Success if successful, BadAlloc if it is unable to obtain necessary  storage for either the return values or work space, BadMatch if the dpy field of the xkb argument is non-NULL and does not match the display argument, and BadLength under certain conditions caused by server or Xkb  implementation errors.



Unable to allocate storage


The length of a request is shorter or longer than that required to minimally contain the arguments


A compatible version of Xkb was not available in the server or an argument has  correct type and range, but is otherwise invalid
