  55         to print.
  56
  57     INPUTS
  58         data - This is passed to the user callback outc as its second argument.
  59         outc - Call this function for every character that should be
  60                 emitted. The function should return EOF on error and
  61                 > 0 otherwise.
  62         format - A printf() format string.
  63         args - A list of arguments for the format string.
