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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@32365 f5534014-38df-0310-8fa8-9805f1628bb7

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 git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@30962 f5534014-38df-0310-8fa8-9805f1628bb7
2009-09-10offset_from_real_beginning() is only called with 0 as second argument, so ↵krj1-2/+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(). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@29844 f5534014-38df-0310-8fa8-9805f1628bb7
2009-08-16Add a new function, tvb_new_subset_remaining(), which is a sligtly optimized ↵krj1-0/+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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@29445 f5534014-38df-0310-8fa8-9805f1628bb7

2007-11-27strcasecmp(), strncasecmp(), g_strcasecmp(), and g_strncasecmp() delendaguy1-2/+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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@23623 f5534014-38df-0310-8fa8-9805f1628bb7

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). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@15758 f5534014-38df-0310-8fa8-9805f1628bb7

2003-06-12Add new routines:guy1-1/+21
tvb_get_string() - takes a tvbuff, an offset, and a length as arguments, allocates a buffer big enough to hold a string with the specified number of bytes plus an added null terminator (i.e., length+1), copies the specified number of bytes from the tvbuff, at the specified offset, to that buffer and puts in a null terminator, and returns a pointer to that buffer (or throws an exception before allocating the buffer if that many bytes aren't available in the tvbuff); tvb_get_stringz() - takes a tvbuff, an offset, and a pointer to a "gint" as arguments, gets the size of the null-terminated string starting at the specified offset in the tvbuff (throwing an exception if the null terminator isn't found), allocates a buffer big enough to hold that string, copies the string to that buffer, and returns a pointer to that buffer and stores the length of the string (including the terminating null) in the variable pointed to by the "gint" pointer. Replace many pieces of code allocating a buffer and copying a string with calls to "tvb_get_string()" (for one thing, "tvb_get_string()" doesn't require you to remember that the argument to "tvb_get_nstringz0()" is the size of the buffer into which you're copying the string, which might be the length of the string to be copied *plus 1*). Don't use fixed-length buffers for null-terminated strings (even if the code that generates those packets has a #define to limit the length of the string). Use "tvb_get_stringz()", instead. In some cases where a value is fetched but is only used to pass an argument to a "proto_tree_add_XXX" routine, use "proto_tree_add_item()" instead. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@7859 f5534014-38df-0310-8fa8-9805f1628bb7
