Overview
The example demonstrates how to event-like wait for a XNET CAN frame to be received.
Description
NI-XNET does not have the ability to trigger an event when a frame arrives. The example shows a suitable workaround to work around the limitation.
The example uses a Frame In Queued session type to build a queue of the specified frame. XNET Read is configured to read just one frame with a timeout of 100 ms, which means that the frame will be returned as soon as the NI-XNET hardware receives the frame. The timeout prevents the application from locking up if the frame is not yet received by the NI-XNET hardware. Therefore the expected timeout error is cleared and the XNET Read is tried again until the frame has been received or the loop is manually stopped.
