Working with the Unix OS

C Libraries
int attrset (chtype attrs) turns on requested attributes
int attroff (chtype attrs) turns off requested attributes
A_BLINK A_BOLD A_ALT A_DIM A_REVERSE A_STANDOUT A_UNDERLINE
int beep()
rings terminal bell
Input Options:
int echo()
int noecho()
int cbreak()
int nocbreak()
break for each character line at a time processing
Output:
Curses assumes stdin and stdout are connected to a terminal.
Once initscr() is called, curses takes over terminal control.
If endwin() is missing, may need to type "stty sane" and terminated with ^J.
