value
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.
