CreatePipeStreams procedure
Create a pair of pipe stream.
Declaration
procedure CreatePipeStreams(var InPipe: TInputPipeStream;
var OutPipe: TOutputPipeStream;
APipeBufferSize: Cardinal=1024)Arguments
InPipe | Contains the read end of the pipe on return. |
OutPipe | Contains the write end of the pipe on return. |
APipeBufferSize |
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.
