It is backed by merely a single <tt>uint64_t</tt> in the kernel, unlike a pipe (which is usually backed by a much larger buffer). It is thus the most lightweight method of IPC available to userspace. The maximum value of the eventfd counter is 2^64-2 (0xfffffffffffffffe), and the minimum (and default) value is 0. In the past, a full pipe was often used to interrupt a th...")
