file that we ourselves have open. In the "safe save" code path for capture files, on Windows temporarily close the file descriptors for the currently-open capture before doing the rename and then, if the rename failed, reopen them, leaving the rest of the wtap and capture_file structures intact. Rename filed_open() to file_fdopen(), to make its name match what it does a bit better (it's an fdopen()-style routine, i.e. do the equivalent of an open with an already-open file descriptor rather than a pathname, in the file_wrappers.c set of routines). Remove the file_ routines from the .def file for Wiretap - they should only be called by code inside Wiretap. Closing a descriptor open for input has no reason to fail (closing a descriptor open for *writing* could fail if the file is on a server and dirty pages are pushed asynchronously to the server and synchronously on a close), so just have file_close() return void. svn path=/trunk/; revision=42961
