96 These functions manipulate attributes on
98 or on the specified window.
99 The attributes that can be manipulated are:
101 .Bl -tag -width "COLOR_PAIR(n)" -compact -offset indent
103 no special attributes are applied
105 characters are displayed in standout mode
107 characters are displayed underlined
109 characters are displayed in inverse video
113 characters are displayed at a lower intensity
115 characters are displayed at a higher intensity
117 characters are added invisibly
119 characters are protected from modification
121 characters are displayed using the alternate character set (ACS)
123 characters are displayed using color pair n.
128 function turns on the attributes specified in
