[implicit_handle(handle_t hMyHandle)]
{
}
The implicit_handle attribute specifies the handle used for functions that do not include an explicit handle as a procedure parameter. If the procedure is remote, the handle will be used as the binding handle for the remote call. The implicit handle may also be used to establish an initial binding for a function that uses a context handle. If the procedure is a serializing procedure, the handle is used as a serializing handle controlling the operation. In the case of type serialization, the handle is used as the serialization handle for all the serialized types.
The implicit_handle attribute specifies a global variable that contains a handle used by any function needing implicit handles.
The implicit binding handle type must be either handle_t (or a type based on handle_t) or a user-defined handle type specified with the handle attribute. The implicit serializing handle must be a type based on handle_t.
If the implicit handle type is not defined in the IDL file or in any files included and imported by the IDL file for the MIDL computer, you must supply the file containing the handle-type definition when you compile the stubs. Use the ACF include statement to include the file containing the handle-type definition.
The implicit_handle attribute can occur once, at most. The implicit_handle attribute can occur only if the auto_handle or explicit_handle attribute does not occur.
