As seen previously, attempts to dereference invalid pointers result in an error, so a method for checking pointer validity is required. To detect invalid pointers, IDL includes the built-in function ptr_valid, which returns true if the argument is a valid pointer, and false otherwise: Sign in...
An object returned from a method call is then passed as an argument to a second method, but the value of the original returned object is null. To prevent the error, check for a return value that is null and call the second method only if the return value is not null.Argument...
