WRONG!!! : Success

How can i change it to

WRONG!!! : WRONG!!!

You can't. The second part of the message is derived from the current value of the "errno" variable. The strings come from message files or directly from libc and cannot be altered.

If you want a completely customized message, just use fprintf instead:
Code:
fprintf (stderr, "WRONG!!! : WRONG!!!\n");
