Look for the lower-level read()/write() interface (Unix unbuffered file
I/O), not the higher-level fread() (C buffered file I/O).

I'm closing this as not a bug, so that it doesn't clog the bug tracker;
but feel free to continue to respond as you have other questions.

Hello,

I am trying to figure out what functions does gzip uses to read/write the
data to/from the files. I saw that for error cases gzip was using *fprintf
(stderr.. *but saw no fread/fscanf functions anywhere in the code.
*
*
Can anyone point out the functions used by gzip to read/write to a file and
in which code file are they.
*
*
Thanks* *
