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.
