IPipeByte interface

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

Methods

The IPipeByte interface has these methods.

Method Description
IPipeByte::Pull Retrieves data of the byte type from the pipe source.
IPipeByte::Push Sends data of the byte type to the pipe source.

Remarks

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.
