xosd_is_onscreen - Returns wether the XOSD window is shown
xosd *xosd_is_onscreen (xosd *osd);
osd_is_onscreen determines weather a XOSD window, is currently being
shown (is mapped to the X display). Because XOSD displays data asynchronously
(see xosd_display(3) for details) it can be difficult to know if data
is being displayed, xosd_is_onscreen solves this problem.
Call xosd_show(3) or xosd_hide(3) to alter the
visibility of the XOSD window.
A 1 is returned if the window is onscreen (mapped), or 0 if it is hidden
(unmapped). On error, -1 is returned and xosd_error is set to indicate
the reason for the error.
- The XOSD window to query.
