The program is here: > https://github.com/AndreasVoellmy/epollbug/blob/master/epollbug.c I finally took a closer look at your code.

If you want to recv() without draining the socket, you can also use the MSG_PEEK flag. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
