41: Gets a character from the terminal and (if necessary)

43: \*(Es
44: Otherwise, the character gotten is returned.
45: If
46: .i noecho

53: .i rawmode

87: This function is used to output every character
88: that
89: .b curses
90: generates.
91: Thus,
92: it can be redefined by the user who wants to do non-standard things
93: with the output.
