xosd_show — Make the XOSD window visible
#include <xosd.h>
int xosd_show(xosd *osd);
xosd_show is called to redisplay data that has been previously displayed using xosd_display(3xosd). The display will remain displayed until the timeout limit, set by calling xosd_set_timeout(3xosd), is reached. The display can be explicitly hidden by calling xosd_hide(3xosd).
On success, a zero is returned. On error, -1 is returned and xosd_error is set to indicate the reason for the error.
