These functions set the current attributes of the window win. The current attributes of win are applied to all characters that are written into it. 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, they will be displayed as the graphic rendition of characters put on the screen.

be visibly different from other text. wstandend turns off the
attributes.
ACS_VLINE and ACS_HLINE, will be used.
Note: vertch and horch can be an integers and will insert the character (with attributes) of the corresponding values.
