OK here is what I have changed my code to -

#include <signal.h>
#include <stdio.h>

void ctrlbrk(fptr)
   int (*fptr)();
{
   signal(SIGINT,fptr);
}

int terminate()
{
	puts("ending function called!");
	exit(0);
}
main()
{
	ctrlbrk(terminate);
	
	while(1)
		puts("I am running on and on!");
}


this compiles with the following  warning

ctrlbrk.c:8: warning: passing arg2 of `signal; from incompatable pointer
type

since it is only a warning when it finishes then runs as I expected it to,
so now my questions change.  Although I am familiar with pointers, I am
not great with them, so how do I fix the warning. Second when you change
the extention and compile it as c++ you get the errors that follows -

ctrlbrk.cc:5: `ftpr' was not declared in this scope
ctrlbrk.cc:6: parse error before `int'
ctrlbrk.cc:7: parse error before `{'
ctrlbrk.cc: In function `int main()':
ctrlbrk.cc:18: warning implicit declaration of function `int ctrlbrk(...)'


why is this?
