be improved if other tasks can be run while a file is being read, or while wai�ng for an external service/program to complete. A channel can be visualized as a pipe, i.e., it has a write end and a read getnameinfo(host::IPAddr) -> String 1107 Performs a reverse-lookup for IP address to return a hostname and service using the opera�ng system's underlying getnameinfo implementa�on. Examples julia> getnameinfo(Sockets
