Wolfram Language Paclet Repository

Community-contributed installable additions to the Wolfram Language

KirillBelov/ CSockets

Sockets powered by pure C

Contributed by: Kirill Belov

Implementation of alternative API for message exchange via TCP protocol.

Installation Instructions

To install this paclet in your Wolfram Language environment, evaluate this code:
PacletInstall["KirillBelov/CSockets"]


To load the code after installation, evaluate this code:
Needs["KirillBelov`CSockets`"]

Details

The package uses functions compiled for LibraryLink.
All package functions start with the CSocket* prefix.
Adds new definitions for functions: 
 SocketListen
 BinaryWrite
 WriteString
 SocketReadyQ
 SocketReadMessage
 Close
 DeleteObject
Development and building the library requires a C compiler, which is installed and available in the Wolfram Language.
