`rename'--rename a file
int rename(const char *OLD, const char *NEW);
int _rename_r(void *REENT,
const char *OLD, const char *NEW);
Use `rename' to establish a new name (the string at NEW) for a file now
known by the string at OLD. After a successful `rename', the file is
no longer accessible by the string at OLD.
If `rename' fails, the file named `*OLD' is unaffected. The
conditions for failure depend on the host operating system.
The alternate function `_rename_r' is a reentrant version. The
extra argument REENT is a pointer to a reentrancy structure.
The result is either `0' (when successful) or `-1' (when the file could
not be renamed).
ANSI C requires `rename', but only specifies that the result on failure
be nonzero. The effects of using the name of an existing file as
`*NEW' may vary from one implementation to another.
Supporting OS subroutines required: `link', `unlink', or `rename'.
