I have a simple server that just serves up a raw PNG file any client that connects. In Julia I wrote the following function to attempt to load that image.
functionReadTeensyImage(server)
sock = Sockets.connect(server,555)
img =load(sock)
close(sock)
return img
end
When calling the above function, I get the error below. From what I can tell, the library assumes the IO object has a lock function unless it is a specific type that does not. This approach seems problematic for other packages to add IO types that don't support locking.
