For you lispers out there

When I'm programming in C, I do something like this:

int result;

result = operation(x,y,z);

if (result) return ERR_CODE;

When I look at lisp, there doesn't seem to be any error evaluation or SEH. How do you handle errors in lisp?

Why would you do that? Just do if (operation (x, y, z))
return ERR_CODE;
