2011-10-03Fix tpo.Guy Harris1-1/+1
svn path=/trunk/; revision=39240
2011-10-03tvb_get_bits{16,32,64} get passed encoding values. Rename the argumentGuy Harris1-4/+4
appropriately; the only valid encoding is big-endian, so we don't actually do anything different with the argument, so as not to break code that passed it a gboolean endian flag. svn path=/trunk/; revision=39237
2011-09-26Move tvb_new_octet_aligned() to tvbuff.c and use it.Anders Broman1-0/+7
svn path=/trunk/; revision=39150
2011-07-11More GLIB_CHECK_VERSION cleanups. Update the minimum GLib/GTK+ versionsGerald Combs1-10/+0
in README.devloper. Remove g_gnuc.h since it's no longer needed. Remove tvbuff_init(), tvbuff_cleanup(), reassemble_init(), and reassemble_cleanup() since they were only used for older GLib versions which didn't support GSlices. Assume we always support the "matches" operator. svn path=/trunk/; revision=37978
2011-07-05Add some additional routine variants that handle string encodings, andGuy Harris1-1/+12
make FT_STRING and FT_UINT_STRING handle string encodings. Get rid of FT_EBCDIC in favor of FT_STRING with ENC_EBCDIC. Add some URLs for DRDA. Clean up some stuff in TN3270 and TN5250, including using ENC_ values for proto_tree_add_item(). svn path=/trunk/; revision=37909
2011-07-03Add a tvb_get_ephemeral_string_enc() routine that's likeGuy Harris1-0/+5
tvb_get_ephemeral_string() but takes an ENC_ value for the character encoding. Use it in the MQ dissector to fetch strings to put, for example, into the Info column, so we properly handle EBCDIC strings there. svn path=/trunk/; revision=37876
2011-06-16Squelch some compiler warnings.Guy Harris1-1/+1

2011-05-27Make TVBs opaque for most users.Jeff Morriss1-69/+6
Convert TVB_RAW_OFFSET() and TVB_GET_DS_TVB() into functions. svn path=/trunk/; revision=37422
2011-05-18- Optimize tvb_get_bits_bufJakub Zawadzki1-2/+2
- Add lsb0 (read: least significant bit is 0) parameter to tvb_get_bits_buf() (not tested, might be buggy...) svn path=/trunk/; revision=37254
2011-05-17Add generic tvb_get_bits_buf() which accepts any no_of_bits.Jakub Zawadzki1-0/+3

2011-01-14Add tvb_get_[n|le]toh[40|48|56]() accessors. Addresses bug 5082.Chris Maynard1-0/+6
svn path=/trunk/; revision=35538
2011-01-12Introduce, and start using, tvb_get_const_stringz(). This function returns aJeff Morriss1-2/+8
pointer to a NULL-terminated string in the TVB. It is no safer than dissectors which call tvb_get_strsize() and then tvb_get_ptr() but it makes it clear that this usage of tvb_get_ptr() is safe. This function is slightly more efficient than tvb_get_ephemeral_stringz()--but only as long as we're not using composite TVBs. svn path=/trunk/; revision=35493
2011-01-03Introduce two new functions for Unicode (UTF-16) string handling:Stephen Fisher1-0/+6
tvb_get_unicode_string() tvb_get_ephemeral_unicode_string() These function like their counterparts, tvb_get_string and tvb_get_epemeral_string, for standard strings. Also update comment on what the first such function, tvb_get_ephemeral_unicode_stringz does regarding updating lengthp. svn path=/trunk/; revision=35344
2010-12-28Add tvb_bcd_dig_to_ep_str()Anders Broman1-1/+18
/* * Given a tvbuff, an offset into the tvbuff, and a length that starts * at that offset (which may be -1 for "all the way to the end of the * tvbuff"), fetch BCD encoded digits from a tvbuff starting from either * the low or high half byte, formating the digits according to an input digit set, * if NUll a default digit set of 0-9 returning "?" for overdecadic digits will be used. * A pointer to the EP allocated string will be returned. * Note a tvbuff content of 0xf is considered a 'filler' and will end the conversion. */ svn path=/trunk/; revision=35286
2010-12-23Introduce new function called tvb_get_ephemeral_unicode_stringz(), whichStephen Fisher1-0/+3
is a unicode (UTF-16) version of tvb_get_ephemeral_stringz(). It scans a tvbuff for a UTF-16 string and converts it to UTF-8 upon return. svn path=/trunk/; revision=35253

2010-05-24Refer to the endianness arguments as "encoding" rather thanGuy Harris1-1/+1
"representation" - we already use "representation" to refer to the text representation of fields. Change some routines with an endianness argument to make it a representation argument instead; svn path=/trunk/; revision=32929

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=4422 From me: Fix a number of instances where the function prototype or the function definition wasn't changed so there was a mismatch thus causing Windows (but not gcc) compilation errors. svn path=/trunk/; revision=32365

About GSM system information type 2quater Modified to use newly defined tvb_get_bits() in tvbuff.c https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=4219 svn path=/trunk/; revision=30962
2009-09-10offset_from_real_beginning() is only called with 0 as second argument, so ↵Kovarththanan Rajaratnam1-2/+2
remove the argument completely. It seems that the second argument only acts as an accumulator allowing offset_from_real_beginning() to call itself recursively. To be consistent offset_from_real_beginning() is renamed to tvb_offset_from_real_beginning(). svn path=/trunk/; revision=29844
2009-08-16Add a new function, tvb_new_subset_remaining(), which is a sligtly optimized ↵Kovarththanan Rajaratnam1-0/+4
version of tvb_new_subset(). The latter can be mapped to the former by tvb_new_subset(tvb, offset, -1 /* backing_length */, -1 /* reported_length */). We can disable some bounds checking because 'backing_length' and 'reported_length' are hardcoded to -1. The current implementation of tvb_new_subset_remaining() only has the THROW_ON(reported_length < 1) check removed when compared to tvb_new_subset(). So there's room for improvement in this function. We should be able to disable some more (redundant) bounds checking. svn path=/trunk/; revision=29445

2009-03-27Introduce two new functions:Stephen Fisher1-0/+10
tvb_get_seasonal_string(); tvb_get_seasonal_stringz(); .. which work the same as the ephemeral versions of the functions, but use se_alloc() instead of ep_alloc(). svn path=/trunk/; revision=27868

2007-11-27strcasecmp(), strncasecmp(), g_strcasecmp(), and g_strncasecmp() delendaGuy Harris1-2/+6
est. Use g_ascii_strcasecmp() and g_ascii_strncasecmp(), and supply our own versions if they're missing from GLib (as is the case with GLib 1.x). In the code to build the list of named fields for Diameter, don't use g_strdown(); do our own g_ascii_-style upper-case to lower-case mapping in the hash function and use g_ascii_strcasecmp() in the compare function. We do this because there is no guarantee that toupper(), tolower(), and functions that use them will, for example, map between "I" and "i" in all locales; in Turkish locales, for example, there are, in both upper case and lower case, versions of "i" with and without a dot, and the upper-case version of "i" is "I"-with-a-dot and the lower-case version of "I" is "i"-without-a-dot. This causes strings that should match not to match. This finishes fixing bug 2010 - an earlier checkin prevented the crash (as there are other ways to produce the same crash, e.g. a bogus dictionary.xml file), but didn't fix the case-insensitive string matching. svn path=/trunk/; revision=23623

tvb_memcpy() be similar, to avoid unnecessarily alignment warnings. Do the same with "ep_tvb_memdup()". svn path=/trunk/; revision=21554

--enable-extra-gcc-checks set. If we turn on -pedantic, try turning on -Wno-long-long as well, so that it's not *so* pedantic that it rejects the 64-bit integral data types that we explicitly require. Constify a bunch of stuff, and make some other changes, to get rid of warnings. Clean up some indentation. svn path=/trunk/; revision=21526

2005-09-11Replace tvb_memcpy() calls that extract IPv4 addresses into a guint32,Guy Harris1-0/+1
and that extract IPv6 addresses into a "struct e_in6_addr", with tvb_get_ipv4() and tvb_get_ipv6() calls - except for some that we remove, by using proto_tree_add_item(), rather than replacing. Have epan/tvbuff.h include epan/ipv6-utils.h, to define "struct e_in6_addr" (not necessary to declare the tvbuff routines, but including it there means "struct e_in6_addr" is guaranteed to be defined before those declarations, so we don't get compiler complaints if we define it *after* those declarations). svn path=/trunk/; revision=15758
2005-09-10Add "tvb_get_ipv4()" and "tvb_get_ipv6()" addresses, to fetch IPv4 andGuy Harris1-0/+9
