+  Name:                                                         pdcsetsc
+
+  Synopsis:
+        int PDC_set_blink(bool blinkon);
+        void PDC_set_title(const char *title);
+
+  Description:
+        PDC_set_blink() toggles whether the A_BLINK attribute sets an
+        actual blink mode (TRUE), or sets the background color to high
+        intensity (FALSE). The default is platform-dependent (FALSE in
+        most cases). It returns OK if it could set the state to match 
+        the given parameter, ERR otherwise. Current platforms also 
+        adjust the value of COLORS according to this function -- 16 for 
+        FALSE, and 8 for TRUE.
+
+        PDC_set_title() sets the title of the window in which the curses
+        program is running. This function may not do anything on some
+        platforms. (Currently it only works in Win32 and X11.)
