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().
Arguments
- socket
a Socket.
Value
An external pointer.
Details
External pointers created by this function are unclassed, hence methods for
contexts such as close() will not work (use reap() instead). Otherwise
they function identically to a Context when passed to all messaging
functions.
