NAME

xosd_is_onscreen - Returns wether the XOSD window is shown

SYNOPSIS

#include <xosd.h>

xosd *xosd_is_onscreen (xosd *osd);

DESCRIPTION

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(3xosd) for details) it can be difficult to know if data is being displayed, xosd_is_onscreen solves this problem.

Call xosd_show(3xosd) or xosd_hide(3xosd) to alter the visibility of the XOSD window.

ARGUMENTS

osd: The XOSD window to query.

RETURN VALUE

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.

ENVIRONMENT

char *xosd_error: A string to a text string describing the error, if one occurred.

HISTORY

The xosd_is_onscreen function first appeared in version 2.1 of the XOSD library.
