PureBasicZMQ

ZMQ Wrapper for PureBasic Programming Language.

Environment

• Windows 10 above (recommend)
• PureBasic 6.0 above (recommend)
• ZeroMQ

How to Build

Building requires PureBasic Compiler and test under Windows 11.
Module features require PureBasic 5.20 and above.

Example

Publisher Server

IncludeFile "../../Core/Enums.pbi"
IncludeFile "../../Core/ZeroMQWrapper.pbi"

UseModule ZeroMQWrapper

Global lpszLibZmqDll.s = "libzmq.dll"
