The Wolfram Language includes built-in network programming, allowing uniform convenient access to both TCP and ZMQ socket functionality on all platforms, as well as a variety of functions for network connectivity and name resolution.

IPAddress — symbolic representation of an IPv4 or IPv6 IP address

URL — symbolic representation of a URL, potentially including a port number (default: 80)

SocketConnect — start a connection to a socket

SocketListen — set up handlers to be run whenever data arrives on a socket

SocketWaitNext ▪ SocketWaitAll ▪ SocketReadyQ

Close — close the connection to a socket

Symbolic Representations

SocketObject — symbolic representation of a connected socket

Sockets — get a list of remote, local, etc. sockets

SocketListener ▪ DeleteObject

Reading from Sockets

ReadString — read as a string all data until a socket is closed

ReadByteArray — read as a byte array all data until a socket is closed

BinaryRead, BinaryReadList — read binary data from a socket

Read, ReadList — read data in specified formats from a socket

SocketReadMessage — read as a byte array a single message from a socket

Writing to Sockets

WriteString — write a string to a socket

BinaryWrite — write binary data to a socket

Write — write data in a specified format to a socket
