NAME
XkbGetControls - Finds the current state of Xkb server controls
SYNOPSIS
Status XkbGetControls (Display *display, unsigned long which, XkbDescPtr xkb);
ARGUMENTS
display
connection to X server
which mask of controls requested
xkb keyboard description for controls information
DESCRIPTION
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 ctrls
structure of the xkb argument. Only those components specified by the which parameter are
copied. Valid values for which are any combination of the masks listed in Table 1 that
have "ok" in the 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.

If xkb->ctrls is NULL, XkbGetControls allocates and initializes it before obtaining the
values specified by which. If xkb->ctrls is not NULL, XkbGetControls modifies only those
portions of xkb->ctrls corresponding to the values specified by which.
XkbGetControls returns Success if successful; otherwise, it returns BadAlloc if it cannot
obtain sufficient storage, BadMatch if xkb is NULL or which is empty, or
BadImplementation.
To free the ctrls member of a keyboard description, use XkbFreeControls.
The num_groups field in the ctrls structure is always filled in by XkbGetControls,
regardless of which bits are selected by which.
RETURN VALUES
Success The XkbGetControls function returns Success if successful.
DIAGNOSTICS
BadAlloc Unable to allocate storage
BadImplementation
Invalid reply from server
BadMatch A compatible version of Xkb was not available in the server or an argument
has correct type and range, but is otherwise invalid
