- Description:
- Normally if you write to a pipe from multiple processes/threads, the messages
will come mixed together unpredictably. Some messages may be interrupted by
parts of messages from other writers. This module takes advantage of some POSIX
specifications to allow multiple writers to send arbitrary data down a pipe in
atomic chunks to avoid the issue.
NOTE: This only works for POSIX compliant pipes on POSIX compliant systems. Also
some features may not be available on older systems, or some platforms.
Under the hood this module will split your message into small sections of
slightly smaller than the PIPE_BUF limit. Each message will be sent as 1 atomic
chunk with a 4 byte prefix indicating what process id it came from, what thread
id it came from, a chunk ID (in descending order, so if there are 3 chunks the
first will have id 2, the second 1, and the final chunk is always 0 allowing a
flush as it knows it is done) and then 1 byte with the length of the data
section to follow.
On the receiving end this module will read chunks and re-assemble them based on
the header data. So the reader will always get complete messages. Note that
message order is not guarenteed when messages are sent from multiple processes
or threads. Though all messages from any given thread/process should be in
order.
