Module unix_socket 

Low-level Unix domain socket primitives.

This module exposes Linux/Android AF_UNIX stream socket mechanics only: bind, listen, accept, connect, chmod for filesystem sockets, peer credentials, and byte I/O through Fd. Callers own all protocol, message framing, authentication policy, daemon behavior, and socket naming.

Abstract socket names are Linux/Android-only. They are encoded with a leading NUL byte in sun_path; interior NUL bytes in the caller-provided abstract name are preserved because the kernel uses the explicit sockaddr length, not C string termination.

Structs

PeerCred

Peer process credentials when the platform exposes them.

UnixListenerFd

Owned non-blocking Unix listener descriptor.

UnixSocketBindOptions

Bind options for a Unix stream listener.

UnixStreamFd

Enums

StaleSocketPolicy

Explicit stale pathname behavior for filesystem socket binds.

UnixConnectResult

Result of starting a non-blocking Unix stream connection.

UnixSocketAddr

Unix socket address.

Functions

bind_unix_listener

chmod_socket_path

chmod_unix_socket
