XkbGetControls(3) XKB FUNCTIONS XkbGetControls(3)
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
