rename---rename a file

Synopsis 
#include <stdio.h>
int rename(const char *old, const char *new);

int _rename_r(void *reent, 
    const char *old, const char *new);
Description
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.


Returns
The result is either 0 (when successful) or -1 (when the file could not be renamed).


Portability
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.
