Transfers data of the long integer type (which is 32 bits wide).
The IPipeLong interface inherits from the IUnknown interface. IPipeLong also has these types of members:
The IPipeByte, IPipeDouble, and IPipeLong interfaces are similar to the standard DCE/RPC pipes. However, the COM implementation of pipes offers more flexibility. With the COM implementation, the basic idea is that the pipe is simply another interface with two methods: Pull and Push. This results in three main benefits:
- A COM pipe is another interface, so it can be received as an out parameter from a method call and then either Pull or Push can be called.
- There are no restrictions on when to call the Pull and Push methods, so a pipe is in reality bidirectional.
- Pipes are interfaces, so the method calls can be asynchronous and follow those rules.
