blocking call to pull_sample become unresponsive when no data available #368

Closed balandongiv closed 4 years ago

balandongiv commented 4 years ago

Setting: In the pull_sample function, the timeout was set to 1 second. Then, deliberately let no data stream coming from the sensor.

Expected: The pull_sample function should return to the calling function whenever the time limit (1 second) is exceeded should there are no data available in the open_streamque.

Problem:

The application stuck infinitely in the lsl_pull_sample_dfunction despite the timeout (1 second) has exceeded.

Question Either I mistakenly understand the role of the timeout var or there is something that I am missing in the sccn setup? Is there any ways to return to the calling function whenever there is no available data upon certain period of time?

Appreciate for any help to address this problem.

Download the latest build solved the problem.

Apparently, even with the latest download from Github repo, the timeout capability is not working with MATLAB 2019a and MATLAB 2020a
