Buffers can be implemented in a fixed memory location in hardware—or by using a virtual data buffer in software, pointing at a location in the physical memory. In all cases, the data stored in a data buffer are stored on a physical storage medium.
The ring buffer is a circular software queue. This queue has a first-in-first-out (FIFO) data characteristic. These buffers are quite common and are found in many embedded systems. Usually, most developers write these constructs from scratch on an as-needed basis.
I am looking for a ring buffer implementation (or pseudocode) in C with the following characteristics:
So far I've been working only with SPSC buffers - one per producer - but I would like to avoid the continuous spinning of the consumer to check for new data over all its input buffers (and maybe to get rid of some marshaling threads in my system).
I develop for Linux on Intel machines.
