Lightweight ring buffer manager

LwRB is a generic FIFO (First In, First Out) buffer library optimized for embedded systems.

Features

Written in C (C11), compatible with stdint.h data types
Platform independent, no architecture specific code
FIFO (First In, First Out) buffer implementation
No dynamic memory allocation, data is static array
Uses optimized memory copy instead of loops to read/write data from/to memory
Thread and interrupt safe when used as pipe with single write and single read entries
Uses C11 atomic operations by default to keep reads and writes race-free, even on architectures whose native word size is smaller than size_t (AVR for instance); can be disabled with LWRB_DISABLE_ATOMIC
Suitable for DMA transfers from and to memory with zero-copy overhead between buffer and application memory
Supports data peek, skip for read and advance for write
Byte-sequence search within buffered data
Optional all-or-nothing read and write operations to avoid partial transfers
Optional per-buffer custom user argument storage
Implements support for event notifications
User friendly MIT license
