rename()

This is a file I/O function, also hardware dependent. It is not implemented in this Compiler.

#include <stdio.h>
  

  int rename(const char *from, const char *to);

  

rename() renames the from file to to. If there already is a to file, rename() does not change anything and returns with an error code.

Non-zero, if an error occurred; zero otherwise.

tmpfile()

tmpnam()
