Certainly mixing file descriptors and streams is dangerous. To the extent that it "works" beyond switching open() to stream with fdopen, it's an extension to the C standards. (It's even uglier when a file is open for read & write.) The main issues are discussed at http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_05.html#tag_02_05_01 and http://www.gnu.org/software/libc/manual/html_node/Stream_002fDescriptor-Precautions.html#Stream_002fDescriptor-Precautions
Eric's website hasn't been updated since 2003, and the links for its svn repo are dead. The last activity on the mailing list was in DEC 2006. If it's being maintained, it would be a good idea to setup a new repo/distribution point and merge the improved versions. It doesn't seem like a good idea to recommend the old website when it seems to have gone stale... FWIW, ImageMagick is a more comprehensive tool, and is actively maintained.
