### 31`` Unix Domain Sockets

This library is unstable; compatibility will not be maintained. See Unstable: May Change Without Warning for more information.

(require unstable/socket) | package: base

> value unix-socket-available? : boolean?

A boolean value that indicates whether unix domain sockets are available and supported on the current platform. The supported platforms are Linux and Mac OS X; unix domain sockets are not supported on Windows and other Unix variants.

> > procedure
> > (unix-socket-connect socket-path) |  | → |  |
> > input-port? |  | output-port?
> socket-path : unix-socket-path?

Connects to the unix domain socket associated with socket-path and returns an input port and output port for communicating with the socket.

> procedure (unix-socket-path? v) → boolean?
> v : any/c

Returns #t if v is a valid unix domain socket path for the current system, according to the following cases:

- If v is a path (path-string?), then the current platform must be either Linux or Mac OS X, and the length of v’s corresponding absolute path must be less than or equal to the platform-specific length (108 bytes on Linux, 104 bytes on Mac OS X). Example: "/tmp/mysocket".

- If v is a bytestring (bytes?), then the current platform must be Linux, v must start with a 0 (NUL) byte, and its length must be less than or equal to 108 bytes. Such a value refers to a socket in the Linux abstract socket namespace. Example: #"\0mysocket".

Otherwise, returns #f.
