How to copy a single file to a different partition in Linux, using C

Question

rename (), link() don't work

Thanks!

Answer 1

Have you tried using standard old C functions?

`fopen` the source on one partition
`fopen` the destination on the other partition

LOOP while `fread` > 0
   `fread` from the source to a buff
   `fwrite` to the dest from a buff

And then close your files (ie. fclose).

This is also more portable.

EDIT: If you wanted it to be really basic why not just use a scripting language (python/bash) and get it done in a few lines.
