You can use the binding attributes to specify how the client connects to the server for remote procedure calls.
| Attribute | Usage |
|---|---|
| async | Defines a handle that allows the caller to make an asynchronous call and return immediately without waiting for results, and then resynchronize with the callee to receive data after the call completes. . |
| auto_handle | Tells MIDL to let the stub code control the binding automatically. This is the default if you don't specify any binding handle. |
| explicit_handle | Lets the client application control the binding with an explicit parameter in each procedure. |
| implicit_handle | Specifies a handle for procedures that do not have an explicit handle parameter. The client application still controls the binding. |
