freopen()

This is a File I/O function. It is not implemented in the Compiler.

  #include <stdio.h>

  

  void freopen(const char *name,

  

               const char *mode,

  

                FILE *f);

  

freopen() opens a file using a specific file descriptor. This can be useful for redirecting stdin, stdout, or stderr. About possible modes, see fopen().

fclose()
