Hi, To summarize, the number of fds is limited to the size of the table, 256 elements at most, this is an estimate from Microsoft that is enough! Solution, as pointed out Tim, is to buffer more data in a single request. It's like nagle algorithm that I will implement, but I think it is not a good solution in my case. Firstly, there's several threads that send CAN frames in accordance with specific conditions... and I should never delay the emission of any frame. Secondly, A CAN frame has a small size ! What is the better solution ?
