2000-09-07Change wtap_read() API so that the data offset is set via a pointer, andGilbert Ramirez1-6/+7
a "keep reading" boolean value is returned from the function. This avoids having to hack around the fact that some file formats truly do have records that start at offset 0. (i4btrace and csids have no file header. Neither does the pppdump-style file that I'm looking at right now). svn path=/trunk/; revision=2392
2000-08-11Miscellaneous code cleaningLaurent Deniel1-1/+3
- add <stdarg.h> or <varargs.h> in snprintf.h and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes - remove the check of multiple inclusions in source (.c) code (there is a bit loss of _cpp_ performance, but I prefer the gain of code reading and maintenance; and nowadays, disk caches and VM are correctly optimized ;-). - protect all (well almost) header files against multiple inclusions - add header (i.e. GPL license) in some include files - reorganize a bit the way header files are included: First: #include <system_include_files> #include <external_package_include_files (e.g. gtk, glib etc.)> Then #include "ethereal_include_files" with the correct HAVE_XXX or NEED_XXX protections. - add some HAVE_XXX checks before including some system header files - add the same HAVE_XXX in wiretap as in ethereal Please forgive me, if I break something (I've only compiled and regression tested on Linux). svn path=/trunk/; revision=2254
2000-05-19Add wtap-int.h. Move definitions relevant to the internal workins of wiretapGilbert Ramirez1-4/+4
to that file, leave public definitions in wtap.h. Rename "union pseudo_header" to "union wtap_pseudo_header". Make the wtap_pseudo_header pointer available in packet_info struct. svn path=/trunk/; revision=1989
2000-05-18Remove the "union pseudo_header" from the "frame_data" structure;Guy Harris1-5/+9
there's no need to keep it around in memory - when the frame data is read in when handing a frame, read in the information, if any, necessary to reconstruct the frame header, and reconstruct it. This saves some memory. This requires that the seek-and-read function be implemented inside Wiretap, and that the Wiretap handle remain open even after we've finished reading the file sequentially. This also points out that we can't really do X.25-over-Ethernet correctly, as we don't know where the direction (DTE->DCE or DCE->DTE) flag is stored; it's not clear how the Ethernet type 0x0805 for X.25 Layer 3 is supposed to be handled in any case. We eliminate X.25-over-Ethernet support (until we find out what we're supposed to do). svn path=/trunk/; revision=1975

2000-03-22In a Network Monitor capture file, get the starting offsets of framesGuy Harris1-1/+8
from the frame table - Network Monitor 2.x, at least, doesn't always write frame N+1 right after frame N. To do that, we need to mallocate a big array to hold the frame table, and free it when we close the capture file; this requires that we have capture-file-type-specific close routines as well as capture-file-type-specific read routines - we let it the pointer to that routine be null if it's not needed. Given that, we might as well get rid of the switch statement in "wtap_close()", in favor of using capture-file-type-specific close routines, as per the comment before that switch statement. svn path=/trunk/; revision=1740

2000-01-13We are obliged to define HAVE_UNISTD_H in "config.h"; to avoid theGuy Harris1-2/+2
hideous problem on FreeBSD 3.[23] (and perhaps other BSDs) if HAVE_UNISTD_H is defined before "zlib.h" is included, turn "file_seek()" into a subroutine defined in a file that *undefines* HAVE_UNISTD_H before including "zlib.h", so that the *only* call to "gzseek()" is made from a file that does not have HAVE_UNISTD_H defined when it includes "zlib.h". Move "file_error()" to that file while you're at it, so it holds all the wrappers that hide the presence or absence of zlib from routines to read capture files. Turn "file.h", which declared those wrapper functions as well as wrapper macros, into "file_wrapper.h" - it belongs with the "file_wrapper.c" file that defines the wrapper functions, not with "file.c" which handles higher-layer file access functions. Remove the comment in "configure.in" that explained why defining HAVE_UNISTD_H was a bad idea, as we're not obliged to define it and work around the problem. (The comment in "file_wrapper.c" explains the workaround.) svn path=/trunk/; revision=1463
2000-01-10Some initial changes for win32 support, but not all.Gilbert Ramirez1-1/+5
Added lots of #ifdef HAVE_*_H wrappers. Added some #defines in config.h.win32 Check for more headers in configure.in Added prototype for inet_aton() in inet_v6defs.h. Changed "BYTE" token (i.e., #define) in ascend-gramamr.y because it conflicts with a windows definition. Use HEXBYTE instead. svn path=/trunk/; revision=1448
