rename

Usage

   #include <stdio.h>
   int rename (const char *oldname,const char *newname);

   ANSI

Description

   Changes the name of a file from oldname to newname. Both oldname and
   newname may contain drive and path names but both names must refer to the
   same drive.

Example 

   #include <stdio.h>
   #include <io.h>
   #include <stdlib.h>

   int main()
   {
       int return_code;
       char *oldname,*newname;

       oldname = "data.fil";
       newname = "file.dat";
       return_code = rename(oldname,newname);
       printf("\n%s %s renamed to %s\n",oldname,
       return_code == 0 ? "was" : "was not",newname);
       return EXIT_SUCCESS;
   }

Return Value

   rename returns a 0 if the file name was successfully changed and non-zero
   if it was not and errno is set.
