nanonext (version 0.9.2)

.context: Technical Utility: Open Context

Description

Open a new Context to be used with a Socket. This function is a performance variant of context, designed to wrap a socket in a function argument when calling request or reply.

Usage

.context(socket)

Value

An external pointer.

Arguments

socket

a Socket.

Details

External pointers created by this function are unclassed, hence methods for contexts such as close will not work. However they function as a Context would when passed to all messaging functions. The context is automatically closed when the object is garbage collected.

Examples

s <- socket("req", listen = "inproc://nanonext")
r <- request(.context(s), "request data")
close(s)
