Why don't you show us the whole source file? And, it wouldn't hurt to tell us what language you're using (one might assume it is C, but with all of the missing pieces needed for a valid C program, that is just a seemingly reasonable guess). And, show us what diagnostics were printed when you tried to compile your source code.

With what you have shown us there are lots of undefined values and undeclared functions without even considering that there is no main() function in your code.

Having code that says // Process error to handle errors, is a great way to ignore errors and have absolutely no idea whether or not anything worked. I would suggest that you actually put code in that section to issue a diagnostic if the rename() failed. And add checks to verify that the strcpy() and stat() calls also worked or print diagnostics and exit if any of them failed.

One might also note that you said your code is intended to copy of file. It does not copy a file. It attempts to move a file (removing the source file if the rename() succeeds); not copy it.

NAME
git-mv - Move or rename a file, a directory, or a symlink SYNOPSIS
git mv <options>... <args>... DESCRIPTION
This script is used to move or rename a file, directory or symlink. git mv [-v] [-f] [-n] [-k] <source> <destination> git mv [-v] [-f] [-n] [-k] <source> ... <destination directory> In the first form, it renames <source>, which must exist and be either a file, symlink or directory, to <destination>. In the second form, the last argument has to be an existing directory; the given sources will be moved into this directory. The index is updated after successful completion, but the change must still be committed. OPTIONS
-f, --force Force renaming or moving of a file even if the target exists -k Skip move or rename actions which would lead to an error condition. An error happens when a source is neither existing nor controlled by GIT, or when it would overwrite an existing file unless -f is given. -n, --dry-run Do nothing; only show what would happen -v, --verbose Report the names of files as they are moved. GIT
Part of the git(1) suite Git 1.7.10.4 11/24/2012 GIT-MV(1)
