I've never seen any such thing, but I've done similar things a lot. I'd say= malloc/read the whole file in and use a decrementing pointer to return the= "previous" character. -- Andrew Duane Juniper Networks 978-589-0551 10 Technology Park Dr aduane@juniper.net Westford, MA 01886-3418 ________________________________________ From: owner-freebsd-hackers@freebsd.org [owner-freebsd-hackers@freebsd.org]= On Behalf Of Julian H.

Hi hackers@, Do we have C libraries with reverse of getchar() [ & maybe read() ] & fopen() [ & maybe open() ] etc, to read from end of file toward beginning ? I dont see anything in the See Also sections. I'm not looking to write, just read. I'm looking for something that returns last char in file as first etc, I'm not interested in wchars etc, I could write some C functions, with seek etc & probably will, if none exist, but no point if they already exist ?
