error_cmprintf_c(log_it.i4.v, format_string.i1a.r
			 [,value_1, value_2, ...])

	This routine displays a formatted, colored error message on
	a TV or graphics window.  The format string should be suitable
	for passing to clib_sprintfx.  A previous call to error_init(_c)
	is necessary.

	format_string	null terminated string which contains the
			characters to be written literally or converted
			as specified by the optional value arguments

			expressions in the format string
