28*7c478bd9Sstevel@tonic-gate  * module:
29*7c478bd9Sstevel@tonic-gate  *	debug.c
30*7c478bd9Sstevel@tonic-gate  *
31*7c478bd9Sstevel@tonic-gate  * purpose:
32*7c478bd9Sstevel@tonic-gate  *	utility routines for debugging filesync (tracing, diagnostics,
33*7c478bd9Sstevel@tonic-gate  *	and error simulation)
34*7c478bd9Sstevel@tonic-gate  *
35*7c478bd9Sstevel@tonic-gate  * contents:
36*7c478bd9Sstevel@tonic-gate  *	showflags	display a word of flags symbolicly
37*7c478bd9Sstevel@tonic-gate  *	dbg_usage	printout usage info for -D switch
38*7c478bd9Sstevel@tonic-gate  *	err_usage	printout usage info for -E switch
39*7c478bd9Sstevel@tonic-gate  *	dbg_set_error	enable an error simulation
40*7c478bd9Sstevel@tonic-gate  *	dbg_check_error	check for error simulation
41*7c478bd9Sstevel@tonic-gate  *
42*7c478bd9Sstevel@tonic-gate  *
43*7c478bd9Sstevel@tonic-gate  * note:
44*7c478bd9Sstevel@tonic-gate  *	there are numerous flag words and bit fields in this
45*7c478bd9Sstevel@tonic-gate  *	program, and it would be horrendous to just print them
46*7c478bd9Sstevel@tonic-gate  *	out in hex (in debugging output).  These routines use
47*7c478bd9Sstevel@tonic-gate  *	a "flaglist" data structure to map between bits and
48*7c478bd9Sstevel@tonic-gate  *	character string names or descriptions.
49*7c478bd9Sstevel@tonic-gate  *
50*7c478bd9Sstevel@tonic-gate  *	a flaglist is merely a list of paired bits and name strings.
