Each key in the " { $snippet "implementations" } " assoc must be the name of an interface defined with " { $link POSTPONE: COM-INTERFACE: } ". The corresponding value must be an array of quotations implementing the methods of that interface in order, including those of its parent interfaces. The " { $snippet "IUnknown" } " methods (" { $link IUnknown::QueryInterface } ", " { $link IUnknown::AddRef } ", and " { $link IUnknown::Release } ") will be defined automatically and must not be specified in the array. These quotations should have stack effects mirroring those of the interface methods being implemented; for example, a method " { $snippet "void foobar ( int foo, int bar )" } " should be implemented with a quotation of effect " { $snippet "( this foo bar -- )" } ". The " { $snippet "this" } " parameter (that is, the leftmost parameter of any COM method) will be automatically converted from an alien pointer to the underlying Factor object before the quotation is invoked.\n\nThe resulting wrapper can be applied to a Factor object using the " { $link com-wrap } " word. The COM interface pointer returned by " { $snippet "com-wrap" } " can then be passed to C functions requiring a COM object as a parameter. The vtables constructed by " { $snippet "<com-wrapper>" } " are stored on the non-GC heap in order to be accessible to C functions; when the wrapper objects and its vtables are no longer needed, the object's resources must be freed using " { $link dispose } ".\n\nExample:" }
