8 * Purpose : zalloc, hash_string, safe_strerror, strcmpic,
9 * strncmpic, and MinGW32 strdup functions. These are
10 * each too small to deserve their own file but don't
11 * really fit in any other file.

39 * $Log: miscutil.h,v $
40 * Revision 1.25 2007/01/18 15:03:20 fabiankeil
41 * Don't include replacement timegm() if
42 * putenv() or tzset() isn't available.
44 * Revision 1.24 2006/08/17 17:15:10 fabiankeil
45 * - Back to timegm() using GnuPG's replacement if necessary.
46 * Using mktime() and localtime() could add a on hour offset if
47 * the randomize factor was big enough to lead to a summer/wintertime
50 * - Removed now-useless Privoxy 3.0.3 compatibility glue.
52 * - Moved randomization code into pick_from_range().
54 * - Changed parse_header_time definition.
55 * time_t isn't guaranteed to be signed and
56 * if it isn't, -1 isn't available as error code.
57 * Changed some variable types in client_if_modified_since()
58 * because of the same reason.
60 * Revision 1.23 2006/07/18 14:48:47 david__schmidt
61 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
62 * with what was really the latest development (the v_3_0_branch branch)
64 * Revision 1.21 2002/04/26 12:55:38 oes
65 * New function string_toupper
67 * Revision 1.20 2002/03/26 22:29:55 swa
68 * we have a new homepage!

80 * Adding string_join()
82 * Revision 1.15 2001/12/30 14:07:32 steudten
83 * - Add signal handling (unix)
84 * - Add SIGHUP handler (unix)
85 * - Add creation of pidfile (unix)
86 * - Add action 'top' in rc file (RH)
87 * - Add entry 'SIGNALS' to manpage
88 * - Add exit message to logfile (unix)
90 * Revision 1.14 2001/11/05 21:43:48 steudten
91 * Add global var 'basedir' for unix os.
93 * Revision 1.13 2001/10/29 03:48:10 david__schmidt
94 * OS/2 native needed a snprintf() routine. Added one to miscutil, brackedted
95 * by and __OS2__ ifdef.
97 * Revision 1.12 2001/10/23 21:27:50 jongfoster
98 * Standardising error codes in string_append
99 * make_path() no longer adds '\\' if the dir already ends in '\\' (this
100 * is just copying a UNIX-specific fix to the Windows-specific part)
102 * Revision 1.11 2001/10/14 22:02:57 jongfoster
103 * New function string_append() which is like strsav(), but running
104 * out of memory isn't automatically FATAL.

123 * Revision 1.5 2001/06/01 10:31:51 oes
124 * Added character class matching to trivimatch; renamed to simplematch
126 * Revision 1.4 2001/05/31 17:32:31 oes
128 * - Enhanced domain part globbing with infix and prefix asterisk
129 * matching and optional unanchored operation

134 * - Introduced chomp()
135 * - Moved strsav() from showargs to miscutil
137 * Revision 1.2 2001/05/29 09:50:24 jongfoster
138 * Unified blocklist/imagelist/permissionslist.
139 * File format is still under discussion, but the internal changes
142 * Also modified interceptor behaviour:
143 * - We now intercept all URLs beginning with one of the following
144 * prefixes (and *only* these prefixes):
146 * * http://ijbswa.sf.net/config/
147 * * http://ijbswa.sourceforge.net/config/
148 * - New interceptors "home page" - go to http://i.j.b/ to see it.
149 * - Internal changes so that intercepted and fast redirect pages
150 * are not replaced with an image.
151 * - Interceptors now have the option to send a binary page direct
152 * to the client. (i.e. ijb-send-banner uses this)
153 * - Implemented show-url-info interceptor. (Which is why I needed
154 * the above interceptors changes - a typical URL is
155 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
156 * The previous mechanism would not have intercepted that, and
157 * if it had been intercepted then it then it would have replaced
160 * Revision 1.1.1.1 2001/05/15 13:59:00 oes
161 * Initial import of version 2.9.3 source tree
