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

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

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

2003-06-12Add new routines:Guy Harris1-1/+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. svn path=/trunk/; revision=7859
2003-05-19More tvb_get_nstringz0() fixes. Timo Sirainen pointed out that BadGerald Combs1-1/+3
Things can happen if we pass a zero buffer length to tvb_get_nstringz0(). Throw an exception if this happens. In various dissectors make sure the tvb_get_nstringz0()'s buffer length is greater than zero. svn path=/trunk/; revision=7688
2003-04-30Modify tvb_get_nstringz*() to behave more like snprintf(). Make changesGerald Combs1-6/+6
where necessary to reflect the new behavior. svn path=/trunk/; revision=7607
2003-02-24Rename "fake_unicode()" to "tvb_fake_unicode()" as it works on a tvbuff,Guy Harris1-1/+8
give it a byte-order argument, and move it to "epan/tvbuff.c". Use it to handle UCS-2 strings in version 1 of the Service Location Protocol. In SRVLOC V1, use registered fields that are already there for SRVLOC V2, and add some as needed. Fix some field names. svn path=/trunk/; revision=7186
2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-5/+5
winapi_cleanup tool written by Patrik Stridvall for the wine project. svn path=/trunk/; revision=6116
2002-07-17Add an extra argument to "tvb_find_line_end()", which specifies what itGuy Harris1-4/+14
should do if it doesn't find an EOL; if FALSE, it behaves as before, returning values that treat the line as ending at the end of the tvbuff, and if TRUE, it returns -1, so its caller can do segment reassembly until it gets the EOL. Add an option to the SMTP dissector to do segment reassembly, and do segment reassembly of the first line. svn path=/trunk/; revision=5891
2002-05-13Add a "tvb_ensure_bytes_exist()", which is like "tvb_bytes_exist()" onlyGuy Harris1-3/+7
it throws the appropriate exception if the bytes don't exist. Use it in the GIOP and ASN.1 code to check whether the bytes to be copied to a buffer exist before allocating the buffer. Make "check_offset_length_no_exception()" check for an overflow, so that it can be used in "tvb_ensure_bytes_exist()" and do all the checking that the code "tvb_ensure_bytes_exist()" replaces did. Make "get_CDR_wchar()" return a "gint", so that if the length octet it fetched has a value between 128 and 255, the length can be returned correctly. Fix some comments not to specify the exception thrown by various routines that can throw various exceptions. svn path=/trunk/; revision=5453
