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.
