type PathOpenSockets 

type PathOpenSockets struct{ *System }

PathOpenSockets is an extension to WASI preview 1 that adds the ability to create TCP sockets. It works by proxying calls to path_open. If fd<0 and the path is of the form: 

<network>:<operation>://<host>:<port>[?options=value[&option=value]*

where network is one of "tcp", "tcp4" or "tcp6", and operation is either "listen" or "dial", the extension will open a socket that either listens on, or connects to, the specified host:port address. Otherwise, the extension passes the arguments to the underlying WASI implementation to open a file or directory as normal.

The following options are available - nonblock=<0|1>: Open the socket in non-blocking mode. Default is 1. - nodelay=<0|1>: Set TCP_NODELAY. Default is 1. - reuseaddr=<0|1>: Set SO_REUSEADDR. Default is 1. - backlog=<N>: Set the listen(2) backlog. Default is 128.

type System 

type System struct {
	// Args are the environment variables accessible via ArgsGet.
	Args []string

	// Environ is the environment variables accessible via EnvironGet.
	Environ []string

	// Realtime returns the realtime clock value.
	Realtime          func(context.Context) (uint64, error)
	RealtimePrecision time.Duration

	// Monotonic returns the monotonic clock value.
	Monotonic          func(context.Context) (uint64, error)
	MonotonicPrecision time.Duration

	// Yield is called when SchedYield is called. If Yield is nil,
	// SchedYield is a noop.
	Yield func(context.Context) error

	// Exit is called with an exit code when ProcExit is called.
	// If Exit is nil, ProcExit is a noop.
	Exit func(context.Context, int) error

	// Raise is called with a signal when ProcRaise is called.
	// If Raise is nil, ProcRaise is a noop.
	Raise func(context.Context, int) error

	// Rand is the source for RandomGet.
	Rand io.Reader

	wasi.FileTable[FD]
	// contains filtered or unexported fields
}
