*
* 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.
*
* Portability X/Open BSD SYS V
