  30         Format a string using C printf() convention, using 'putch'
  31         as character output function.
  32
  33     INPUTS
  34         putch  - A pointer to the output function
  35         format - A format string
  36         args   - A list of arguments
  37
  38         A character output function needs to be declared as:
  39
  40         int myPutCh(int char, void *KernelBase)
  41
  42         It is expected to return 1 on success and 0 on failure.
