HylaFAX is only using it in one source file: hfaxd/FileTransfer.c++. http://hylafax.cvs.sourceforge.net/viewvc/*checkout*/hylafax/hylafax/hfaxd/FileTransfer.c%2B%2B You'll see that it's used in several places. Recognize that most of the code there was written by Sam Leffler, so it's going to have a familiar flavor to it. :-) Thanks, Lee.
