Synopsis
  char *XResourceManagerString(display)
	Display *display;

Arguments

Description
  XResourceManagerString()  returns the RESOURCE_MANAGER property from the root window of screen zero, which was returned when the connection
  was opened using XOpenDisplay().  The property is converted from type STRING to the current locale.  The conversion is  identical  to  that
  produced  by XmbTextPropertyToTextList() for a singleton STRING property.  The returned string is owned by Xlib, and should not be freed by
  the client.  Note that the property value must be in a format that is acceptable to XrmGetStringDatabase().  If no property exists, NULL is
  returned.
