+
+  Description:
+        These functions manipulate the current attributes and/or colors 
+        of the named window.  These attributes can be any combination 
+        of A_STANDOUT, A_REVERSE, A_BOLD, A_DIM, A_BLINK, A_UNDERLINE.
+
+        These constants are defined in <curses.h> and can be combined
+        with the bitwise-OR operator (|).
+
+        The current attributes of a window are applied to all chtypes 
+        that are written into the window with waddch(). Attributes are 
+        a property of the chtype, and move with the character through 
+        any scrolling or insert/delete operations.
+
+        attrset() sets the current attributes of the given window to 
+        attrs. attroff() turns off the named attributes without 
+        affecting any other attributes; attron() turns them on. 
+        color_set() sets the window color to the value of color_pair.
+
+        standout() is the same as attron(A_STANDOUT). standend() is the 
+        same as attrset(A_NORMAL); that is, it turns off all attributes.
+
+  Return Value:
+        All functions return OK on success and ERR on error.
