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(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.

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.

AUTHORS

       didn't write this document.
