NAME
	Fault -- Returns the text associated with a DOS error code (V36)

   SYNOPSIS
	len = Fault(code, header, buffer, len)
	D0           D1     D2      D3    D4

	LONG Fault(LONG, STRPTR, STRPTR, LONG)

   FUNCTION
	This routine obtains the error message text for the given error code.
	The header is prepended to the text of the error message, followed
	by a colon.  Puts a null-terminated string for the error message into
	the buffer.  By convention, error messages should be no longer than 80
	characters (+1 for termination), and preferably no more than 60.
	The value returned by IoErr() is set to the code passed in.  If there
	is no message for the error code, the message will be "Error code
	<number>n".

	The number of characters put into the buffer is returned, which will
	be 0 if the code passed in was 0.

   INPUTS
	code   - Error code
	header - header to output before error text
	buffer - Buffer to receive error message.
	len    - Length of the buffer.

   RESULT
	len    - number of characters put into buffer (may be 0)

	IoErr(), SetIoErr(), PrintFault()

   BUGS
	In older documentation, the return was shown as BOOL success.  This
	was incorrect, it has always returned the length.
