|
|
* 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.
