NAME¶
XkbGetCompatMap - Fetch any combination of the current compatibility map
components from the server
SYNOPSIS¶
Status
XkbGetCompatMap (Display *display, unsigned int
which, XkbDescRec *xkb);
ARGUMENTS¶
- - display
- connection to server
- - which
- mask of compatibility map components to fetch
- - xkb
- keyboard description where results placed
DESCRIPTION¶
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.

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.
DIAGNOSTICS¶
- BadAlloc
- Unable to allocate storage
- BadLength
- The length of a request is shorter or longer than that
required to minimally contain the arguments
- BadMatch
- A compatible version of Xkb was not available in the server
or an argument has correct type and range, but is otherwise invalid
