CreatePipeStreams

Create a pair of pipe stream.

Declaration

Source position: pipes.pp line 54

procedure CreatePipeStreams(

  var InPipe: TInputPipeStream;

  var OutPipe: TOutputPipeStream

);

Arguments

InPipe

  

Contains the read end of the pipe on return

OutPipe

  

Contains the write end of the pipe on return.

Description

CreatePipeStreams creates a set of pipe file descriptors with CreatePipeHandles, and if that call is successful, a pair of streams is created: InPipe and OutPipe.

On some systems (notably: windows) the size of the buffer to be used for communication between 2 ends of the buffer can be specified in the APipeBufferSize parameter. This parameter is ignored on systems that do not support setting the buffer size.

Errors

If no pipe handles could be created, an EPipeCreation exception is raised.
