Single Producer Single Consumer Packet Buffer
|
||
|
|
=============================================
|
||
|
|
|
||
|
|
A :dfn:`Single Producer Single Consumer Packet Buffer (SPSC_PBUF)` is a circular
|
||
|
|
buffer, whose contents are stored in first-in-first-out order. Variable size
|
||
|
|
packets are stored in the buffer. Packet buffer works under assumption that there
|
||
|
|
is a single context that produces packets and a single context that consumes the
|
||
|
|
data.
|
||
|
|
|
||
|
|
Implementation is focused on performance and memory footprint.
|
||
|
|
|
||
|
|
Packets are added to the buffer using :c:func:`spsc_pbuf_write` which copies a
|
||
|
|
data into the buffer. If the buffer is full error is returned.
|
||
|
|
|
||
|
|
Packets are copied out of the buffer using :c:func:`spsc_pbuf_read`.
