PipeReaders
NAME
PipeReaders - read and buffer input from pipelines
SYNOPSIS
PROCEDURE Spawn(VAR s: Streams.Stream; pipe: Streams.Stream);
DESCRIPTION
PipeReaders
provides a Streams implementation that continuously reads all
available input from a given stream, buffers it, and makes it available
as soon as it is convenient to process it. This allows to avoid deadlocks
in case where the producer could get suspended because its output is
not consumed.
This module preserves the input packets (see Streams.ReadPacket)
as long their size does not exceed the internal buffer size.
StreamConditions
is supported.
Spawn
spawns off a task that reads from pipe and makes its input
available through s. This task will run until s is closed.
DIAGNOSTICS
Error events are forwarded from pipe to s.
