fstrm

Frame Streams implementation in C

fstrm is a C implementation of Frame Streams that includes a lockless circular queue implementation and exposes library interfaces for setting up a dedicated Frame Streams I/O thread and asynchronously submitting data frames for transport from worker threads. Frame Streams is a protocol that allows for the transport of arbitrarily encoded data payload sequences with just 4 bytes per data frame. Frame Streams does not specify an encoding format for frames and can be used with data serialization formats that produces byte sequences, such as Protocol Buffers, XML, JSON, MessagePack, YAML, etc. Frame Streams can be used both as a streaming transport over a reliable byte stream socket (TCP, AF_UNIX, TLS, etc.) for data in motion, as well as a file format for data at rest. A "Content Type" header identifies the type of payload being carried over an individual Frame Stream and allows cooperating programs to determine how to interpret a given sequence of data payloads.
