.I \- which
mask of controls requested
.TP
.I \- xkb
keyboard description for controls information
.SH DESCRIPTION
.LP
.I XkbGetControls
queries the server for the requested control information, waits for a reply, and
then copies the server's values for the requested information into the
.I ctrls
structure of the
.I xkb
argument. Only those components specified by the
.I which
parameter are copied. Valid values for
.I which
are any combination of the masks listed in Table 1 that have "ok" in the
.I which
column.
Table 1 shows the actual values for the individual mask bits used to select
controls for
modification and to enable and disable the control. Note that the same mask bit
is used to
specify general modifications to the parameters used to configure the control
(which), and to
enable and disable the control (enabled_ctrls). The anomalies in Table 1 (no
"ok" in column)
are for controls that have no configurable attributes; and for controls that are
not boolean
controls and therefore cannot be enabled or disabled.

.TE
If
.I xkb->ctrls
is NULL,
.I XkbGetControls
allocates and initializes it before obtaining the values specified by
.I which.
If
.I xkb->ctrls
is not NULL,
.I XkbGetControls
modifies only those portions of
.I xkb->ctrls
corresponding to the values specified by
.I which.
.I XkbGetControls
returns Success if successful; otherwise, it returns BadAlloc if it cannot
obtain sufficient storage, BadMatch if
.I xkb
is NULL or
.I which
is empty, or BadImplementation.
To free the
.I ctrls
member of a keyboard description, use
.I XkbFreeControls.
The
.I num_groups
field in the
.I ctrls
structure is always filled in by
.I XkbGetControls,
regardless of which bits are selected by
.I which.
.SH "RETURN VALUES"
.TP 15
Success
The
.I XkbGetControls
function returns Success if successful.
.SH DIAGNOSTICS
.TP 15
.B BadAlloc
Unable to allocate storage
.TP 15
.B BadImplementation
Invalid reply from server
.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
