/* util.c
* Utility routines
*
Merge in the final code to make Ethereal run on Win32, compiled with MSVC 6.0 and 'nmake', the make tool that comes with MSVC. It compiles, links, and runs. It doesn't run correctly. There's a problem when reading files. I'm getting short reads. I'm not linking in zlib or libsnmp because it first needs to be debugged. I changed the plugin code to use gmodule instead of libltdl, but the Unix build still links ethereal against libltdl. I'll fix that tonight; sorry about leaving it in such a sad state, but I wanted to check in this code before I left work on a Friday night. Ethereal still works, but the building is less than optimal. svn path=/trunk/; revision=1479

Make a "create_tempfile()" routine that constructs the template to be used by "mkstemp()" into a buffer supplied as an argument, trying several directories for the tempfile, in the same fashion that the BSD (and probably other) "tempnam()" routines do. Have that routine cope with temporary-file directory names that don't end with "/", as "P_tmpdir" doesn't necessarily end with "/" (and doesn't, in GNU "libc" 2.x, at least on Linux); thanks to Gilbert Ramirez for catching this one, and supplying the code to cope with that.

Capturing packets from ethereal now saves the capture in an "anonymous" buffer. That is, it's a random name chosen by tempnam(), unknown to the user. If the user decides to save that trace, he then uses File | Save to save it to a file. File | Save As lets him make a copy of his named trace file as well. I also updated my e-mail address in the various credit locations. svn path=/trunk/; revision=242

Some initial changes for win32 support, but not all. 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

A "character encoding" variable is now set per packet. The existence of SNA in a packet changes the character encoding from the default ASCII to EBCDIC. The hex-printing routines in the GUI code and in the printing code convert to EBCDIC if appropriate. svn path=/trunk/; revision=1089
