.SH SYNOPSIS

.I \- which
mask of compatibility map components to fetch
.TP
.I \- xkb
keyboard description where results placed
.SH DESCRIPTION
.LP
When another client modifies the compatibility map, you are notified if you have
selected for XkbCompatMapNotify events.
.I 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.
.I XkbGetCompatMap
fetches the components of the compatibility map specified in
.I which
from the server specified by
.I display
and places them in the
.I compat
structure of the keyboard description
.I xkb.
Valid values for
.I which
are an inclusive OR of the values shown in Table 1.

XkbSymInterpMask (1<<0) Symbol interpretations
XkbGroupCompatMask (1<<1) Group maps
XkbAllCompatMask (0x3) All compatibility map components
.TE
If no compatibility map structure is allocated in
.I xkb
upon entry,
.I XkbGetCompatMap
allocates one. If one already exists, its contents are overwritten with the
returned results.
.I XkbGetCompatMap
fetches compatibility map information for the device specified by the
.I device_spec
field of
.I xkb.
Unless you have specifically modified this field, it is the default keyboard
device.
.I 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
.I dpy
field of the
.I xkb
argument is non-NULL and does not match the
.I display
argument, and BadLength under certain conditions caused by server or Xkb
implementation errors.
.SH DIAGNOSTICS
.TP 15
.B BadAlloc
Unable to allocate storage
.TP 15
.B BadLength
The length of a request is shorter or longer than that required to minimally contain the arguments
.TP 15
.B BadMatch
A compatible version of Xkb was not available in the server or an argument has
correct type and range, but is otherwise invalid
