SYNOPSIS

       int attroff(
	       int attrs ); int wattroff(
	       WINDOW *win,
	       int attrs ); int attron(
	       int attrs ); int wattron(
	       WINDOW *win,
	       int attrs ); int attrset(
	       int attrs ); int wattrset(
	       WINDOW *win,
	       int attrs ); int standend(
	       void ); int wstandend(

LIBRARY

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       attroff, wattroff, attron, wattron, attrset, wattrset, standend, wstandend, standout, wstandout:  XCURSES4.2

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

DESCRIPTION
       These routines manipulate the current attributes of the current or specified window. The current attributes of a window are applied to  all
       characters  that are written into the window with waddch, waddstr and wprintw. Attributes are a property of the character and move with the
       character through any scrolling and insert/delete line/character operations. To the extent possible on the particular terminal,	attributes
       are displayed as the graphic rendition of characters put on the screen.

       The  routine attrset sets the current attributes of the window to attrs. The routine attroff turns off the named attributes without turning
       any other attributes on or off. The routine attron turns on the named attributes without affecting any  others.	The  routine  standout	is
       equivalent to attron(A_STANDOUT). The routine standend is equivalent to attrset(0); that is, standend turns off all attributes.

   Attributes
       The following video attributes, which are defined in <curses.h>, can be passed to the routines attron, attroff, and attrset. The attributes
       also can be combined (by using an inclusive OR operation) with characters passed to addch.

       A_ALTCHARSET   Alternate character set
       A_BLINK	      Blinking
       A_BOLD	      Extra bright or bold
       A_DIM	      Half bright
       A_INVIS	      Invisible
       A_PROTECT      Protected
       A_REVERSE      Reverse video
       A_STANDOUT     Best highlighting mode of the terminal.
       A_UNDERLINE    Underlining

NOTES
       The header file <curses.h> automatically includes the header file <stdio.h>.

       Note that attroff, attron, attrset, standend, and standout may be macros.

RETURN VALUES
       These routines always return OK.
