XkbGetNamedIndicator(3) XKB FUNCTIONS XkbGetNamedIndicator(3)NAMEXkbGetNamedIndicator - Look up the indicator map and other information
for an indicator by name
Bool XkbGetNamedIndicator (Display *dpy, unsigned int dev_spec, Atom
name, int *ndx_rtrn, Bool *state_rtrn, XkbIndicatorMapPtr
map_rtrn, Bool *real_rtrn);
- dpy connection to the X server
keyboard device ID, or XkbUseCoreKbd
- name name of the indicator to be retrieved
backfilled with the index of the retrieved indicator
backfilled with the current state of the retrieved indicator
backfilled with the mapping for the retrieved indicator
backfilled with True if the named indicator is real (physical)
Xkb also allows applications to refer to indicators by name. Use
XkbGetNames to get the indicator names. Using names eliminates the need
for hard-coding bitmask values for particular keyboards. For example,
instead of using vendor-specific constants such as WSKBLed_ScrollLock
mask on Digital workstations or XLED_SCROLL_LOCK on Sun workstations,
you can instead use XkbGetNamedIndicator to look up information on the
indicator named "Scroll Lock."
If the device specified by device_spec has an indicator named name,
XkbGetNamedIndicator returns True and populates the rest of the parame‐
ters with information about the indicator. Otherwise, XkbGetNamedIndi‐
cator returns False.
The ndx_rtrn field returns the zero-based index of the named indicator.
This index is the bit position to use in any function call that
requires a mask of indicator bits, as well as the indicator's index
into the XkbIndicatorRec array of indicator maps. state_rtrn returns
the current state of the named indicator (True = on, False = off).
map_rtrn returns the indicator map for the named indicator. In addi‐
tion, if the indicator is mapped to a physical LED, the real_rtrn
parameter is set to True.
Each of the " _rtrn " arguments is optional; you can pass NULL for any
unneeded " _rtrn " arguments.
True The XkbGetNamedIndicator function returns True if the
device specified by device_spec has an indicator named
False The XkbGetNamedIndicator function returns False if the
device specified by device_spec does not have an indica‐
tor named name.
