Unlike a file, you can't directly address portions of a communication stream. What would lseek do? Sockets have semantics that are very sequential in nature. mmap is not a good fit. How would you use mmap on a pipe? -- Matt Thomas Internet: thomas@lkg.dec.com U*X Networking WWW URL: http://ftp.dec.com/%7Ethomas/ Digital Equipment Corporation Disclaimer: This message reflects my Littleton, MA own warped views, etc.
