You can some mistakes in your code:
The first mistakes in line - 'kill(getpid(),-9);'
In the Unix basic systems have not a signal with id '-9', but have a signal with id '9'.
Try with int k=kill(getpid(),SIGKILL);
The second mistakes is similar that first - 'int r=raise(-9);' .
The third mistakes:
You don't kill process whit 'raise', because process one killed from 'k=kill(getpid(),SIGKILL);'
Do you really need killing a current process ?

LIBRARY
Standard C Library (libc.so, libc.a)
