xosd_is_onscreen - Returns wether the XOSD window is shown

osd    The XOSD window to query.

       The XOSD library was originally written by André Renaud and is currenly maintained by Tim Wright, who al‐
       so wrote the xosd_is_onscreen function. Michael JasonSmith thinks he wrote  this  document,  but  is  not
       sure; drop Micahel an email (<mike@ldots.org>) if you think he didn't write this document.

       There are no known bugs with xosd_is_onscreen. Bug reports can be sent to <xosd@ignavus.net>.

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.

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

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

       A  1 is returned if the window is onscreen (mapped), or 0 if it is hidden (unmapped). On error, -1 is re‐
       turned and xosd_error is set to indicate the reason for the error.
