reverse of getchar() read() open() fopen() ?

[Andrew Duane]

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.

Subject: reverse of  getchar() read() open() fopen() ?

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 ?

Cheers,
Julian
