Client Socket Pool

A set of functions to manage connections in a socket connection pool { ({type, host, name}, [ss_ptr]) } This module provides a single pool per instance of evlua/evluaserver The module Socket connection pool repository(evpoolrepos) provides an interface to manage multiple repositories per instance of evlua/evluaserver {(pool_name, pool)} and is a better implementation of socket connection pool. It is recommended to use that interface rather than this.
