The interface pointer and a specification of the method to be called.
A form which is evaluated to yield a COM
i-dispatch interface pointer.
A symbol which names the property getter method. It is not evaluated.
Arguments to the method (see Data conversion when calling Automation methods for details).
Values from the method (see Data conversion when calling Automation methods for details).
call-dispatch-get-property macro is used to invoke an Automation property getter method from Lisp. The dispinterface-ptr should be a COM interface pointer for the
i-dispatch interface. The appropriate Automation property getter method, chosen using dispinterface-name and method-name, is invoked after evaluating each arg. The args must be values that are suitable for the method and of types compatible with Automation. The values returned are as specified by the method signature. In general, property getter methods take no arguments and return the value of the property, but see Data conversion when calling Automation methods for more details.
There is also
setf expander for
call-dispatch-get-property, which can be used as an alternative to the
