hostreceive

Hostreceive is a term used in various software projects to denote a receiver component that accepts inbound data from a host system. There is no formal standard named hostreceive, and the exact behavior depends on the project, platform, and communication channel.

Role and behavior: It typically implements a receive path that collects bytes or messages, performs initial framing or decoding, validates integrity, and passes data to higher levels for processing. It may also enforce flow control, buffering, and error handling, and may provide hooks for security checks such as authentication or message signing.

Common contexts: In embedded systems, hostreceive may refer to a UART, USB, or network interface at the device side that handles commands from a host PC. In virtualization or container environments, hostreceive-like components manage inter-process communication channels between host and guest, often using virtio, shared memory, or socket-based transport. In client-server applications, hostreceive can be a listener socket or a message queue consumer that receives requests sent from a host controller.

Implementation notes: Designers typically consider data framing, endianness, serialization formats (JSON, protobuf, etc.), idempotency, and concurrency control. Robust implementations include timeouts, retry logic, and security measures to prevent spoofing or tampering.
