High Quality Content by WIKIPEDIA articles! A futex (short for "fast userspace mutex") is a Linux construct that can be used to implement basic locking, or as a building block for higher-level locking abstractions such as semaphores and POSIX mutexes or condition variables. A futex consists of a kernelspace wait queue that is attached to a userspace aligned integer. Multiple processes or threads operate on the integer entirely in user space (using atomic operations to avoid interfering with one another), and only resort to relatively expensive system calls to request operations on the wait queue (for example to wake up waiting processes, or to put the current process on the wait queue). A properly programmed futex-based lock will not use system calls except when the lock is contended; since most operations do not require arbitration between processes, this will not happen in most cases.
