C++ (Cpp) os_protect_memory Examples

Example #1

int protect_memory(unsigned long addr, unsigned long len, int r, int w, int x,
		   int must_succeed)
{
	int err;

	err = os_protect_memory((void *) addr, len, r, w, x);
	if(err < 0){
                if(must_succeed)
			panic("protect failed, err = %d", -err);
		else return(err);
	}
	return(0);
}
