/* xxd: my hexdump facility. jw * * 2.10.90 changed to word output * 3.03.93 new indent style, dumb bug inserted and fixed. * -c option, mls * 26.04.94 better option parser, -ps, -l, -s added. * 1.07.94 -r badly needs - as input file. Per default autoskip over * consecutive lines of zeroes, as unix od does. * -a shows them too. * -i dump as c-style #include "file.h" * 1.11.95 if "xxd -i" knows the filename, an 'unsigned char filename_bits[]' * array is written in correct c-syntax. * -s improved, now defaults to absolute seek, relative requires a '+'. * -r improved, now -r -s -0x... is supported. * change/suppress leading '\0' bytes. * -l n improved: stops exactly after n bytes. * -r improved, better handling of partial lines with trailing garbage. * -r improved, now -r -p works again! * -r improved, less flushing, much faster now! (that was silly) * 3.04.96 Per repeated request of a single person: autoskip defaults to off. * 15.05.96 -v added. They want to know the version. * -a fixed, to show last line inf file ends in all zeros. * -u added: Print upper case hex-letters, as preferred by unix bc. * -h added to usage message. Usage message extended. * Now using outfile if specified even in normal mode, aehem. * No longer mixing of ints and longs. May help doze people. * Added binify ioctl for same reason. (Enough Doze stress for 1996!) * 16.05.96 -p improved, removed occasional superfluous linefeed. * 20.05.96 -l 0 fixed. tried to read anyway. * 21.05.96 -i fixed. now honours -u, and prepends __ to numeric filenames. * compile -DWIN32 for NT or W95. George V. Reilly, * -v improved :-) * support --gnuish-longhorn-options * 25.05.96 MAC support added: CodeWarrior already uses ``outline'' in Types.h * which is included by MacHeaders (Axel Kielhorn). Renamed to * xxdline(). * 7.06.96 -i printed 'int' instead of 'char'. *blush* * added Bram's OS2 ifdefs... * 18.07.96 gcc -Wall @ SunOS4 is now slient. * Added osver for MSDOS/DJGPP/WIN32. * 29.08.96 Added size_t to strncmp() for Amiga. * 24.03.97 Windows NT support (Phil Hanna). Clean exit for Amiga WB (Bram) * 02.04.97 Added -E option, to have EBCDIC translation instead of ASCII * (azc10@yahoo.com) * 22.05.97 added -g (group octets) option (jcook@namerica.kla.com). * 23.09.98 nasty -p -r misfeature fixed: slightly wrong output, when -c was * missing or wrong. * 26.09.98 Fixed: 'xxd -i infile outfile' did not truncate outfile. * 27.10.98 Fixed: -g option parser required blank. * option -b added: 01000101 binary output in normal format. * 16.05.00 Added VAXC changes by Stephen P. Wall * 16.05.00 Improved MMS file and merge for VMS by Zoltan Arpadffy * 2011 March Better error handling by Florian Zumbiehl. * 2011 April Formatting by Bram Moolenaar * 08.06.2013 Little-endian hexdump (-e) and offset (-o) by Vadim Vygonets. * 11.01.2019 Add full 64/32 bit range to -o and output by Christer Jensen. * * (c) 1990-1998 by Juergen Weigert (jnweiger@informatik.uni-erlangen.de) * * I hereby grant permission to distribute and use xxd * under X11-MIT or GPL-2.0 (at the user's choice). * * Small changes made afterwards by Bram Moolenaar et al. * * Distribute freely and credit me, * make money and share with me, * lose money and don't ask me. */ /* Visual Studio 2005 has 'deprecated' many of the standard CRT functions */ #if _MSC_VER >= 1400 # define _CRT_SECURE_NO_DEPRECATE # define _CRT_NONSTDC_NO_DEPRECATE #endif #if !defined(CYGWIN) && defined(__CYGWIN__) # define CYGWIN #endif #include <stdio.h> #ifdef VAXC # include <file.h> #else # include <fcntl.h> #endif #if defined(WIN32) || defined(CYGWIN) # include <io.h> /* for setmode() */ #else # ifdef UNIX # include <unistd.h> # endif #endif #include <stdlib.h> #include <string.h> /* for strncmp() */ #include <ctype.h> /* for isalnum() */ #include <limits.h> #if __MWERKS__ && !defined(BEBOX) # include <unix.h> /* for fdopen() on MAC */ #endif /* This corrects the problem of missing prototypes for certain functions * in some GNU installations (e.g. SunOS 4.1.x). * Darren Hiebert <darren@hmi.com> (sparc-sun-sunos4.1.3_U1/2.7.2.2) */ #if defined(__GNUC__) && defined(__STDC__) # ifndef __USE_FIXED_PROTOTYPES__ # define __USE_FIXED_PROTOTYPES__ # endif #endif #ifndef __USE_FIXED_PROTOTYPES__ /* * This is historic and works only if the compiler really has no prototypes: * * Include prototypes for Sun OS 4.x, when using an ANSI compiler. * FILE is defined on OS 4.x, not on 5.x (Solaris). * if __SVR4 is defined (some Solaris versions), don't include this. */ #if defined(sun) && defined(FILE) && !defined(__SVR4) && defined(__STDC__) # define __P(a) a /* excerpt from my sun_stdlib.h */ extern int fprintf __P((FILE *, char *, ...)); extern int fputs __P((char *, FILE *)); extern int _flsbuf __P((unsigned char, FILE *)); extern int _filbuf __P((FILE *)); extern int fflush __P((FILE *)); extern int fclose __P((FILE *)); extern int fseek __P((FILE *, long, int)); extern int rewind __P((FILE *)); extern void perror __P((char *)); # endif #endif extern long int strtol(); extern long int ftell(); char version[] = "xxd V1.10 27oct98 by Juergen Weigert"; #ifdef WIN32 char osver[] = " (Win32)"; #else char osver[] = ""; #endif #if defined(WIN32) # define BIN_READ(yes) ((yes) ?
