IPipeByte interface (objidl.h)

Transfers data of the byte type (which is 8 bits wide).


The IPipeByte interface inherits from the IUnknown interface. IPipeByte also has these types of members:


The IPipeByte interface has these methods.


Retrieves data of the byte type from the pipe source. (IPipeByte.Pull)

Sends data of the byte type to the pipe source. (IPipeByte.Push)


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.
For more information, see Pipes in the RPC documentation.
