Function Documentation

◆ elektraIoAdapterZeroMqAttach()

ElektraIoAdapterZeroMqHandle* elektraIoAdapterZeroMqAttach ( void *  socket,
ElektraIoInterface ioBinding,
ElektraIoAdapterZeroMqCallbackType  type,
ElektraIoAdapterZeroMqCallback  callback,
void *  context 
)

Attach to ZeroMq socket.

The callback is called whenever socket is readable or writable (depending on type) and data can be processed. The callback should not do blocking calls (e.g. use ZMQ_DONTWAIT for zmq_*recv()). Since ZeroMq guarantees that multipart messages arrive at once, data will be available. New adapter instances are enabled.

Parameters
