But this is TCP:

This has been answered by previous posters
Keep pointers to your packetBuffers in a circular buffer. When a new
packet comes in, add it to the front of the buffer. When you're ready
to process a packet, remove it from the end of the buffer.
Some testing should determine how big your buffer needs to be.

I assume by "local socket" you mean either a UNIX domain socket or just a
regular TCP socket on the local machine? If so, just using regular read & write

What makes you think that? If the buffers f
Hi, All,
I have a need to read some data from a local socket, which serves for
IPC. And data may come very quickly, so (AFAIU) inner socket buffer
might overflow, so a portion of data might be lost. I don't see a way
how to define an inner system buffer size, so the only I can is to do
