39*7c478bd9Sstevel@tonic-gate  * The DPRINTF macro can be used by setting the debug_print_level to the
40*7c478bd9Sstevel@tonic-gate  * appropriate debugging level.  The debug levels are defined in each source
41*7c478bd9Sstevel@tonic-gate  * file where this header file is included.  The scoping of debug_info,
42*7c478bd9Sstevel@tonic-gate  * and debug_print_level is to the file which included the header file.
43*7c478bd9Sstevel@tonic-gate  * If multiple levels need to be output, the values can be 'ored'
44*7c478bd9Sstevel@tonic-gate  * together into debug_print_level.  If debug_print_line's bit 1 is set, the
45*7c478bd9Sstevel@tonic-gate  * line number of the debugging statement is printed out. If it has
46*7c478bd9Sstevel@tonic-gate  * bit 2 set, the macro will drop into either the debugger or the OBP PROM.
