I tried with that it didn't work. It works when I add the 
#include <netdb.h>

however when I add that library, it doesn't allow the "fprintf" and
"strupr" to work, any ideas?

Got the following error 

/tmp/ccD8SAtf.o(.text+0x37f): In function `main':
: undefined reference to `fprint'

appears as "fprint" even when I put "fprintf"

any ideas?
