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.
