atomic_ops
atomic_ops(3C) Standard C Library Functions atomic_ops(3C)
NAME
atomic_ops - atomic operations
SYNOPSIS
#include <atomic.h>
DESCRIPTION
This collection of functions provides atomic memory operations. There are 8 different classes of atomic operations:
atomic_add(3C) These functions provide an atomic addition of a signed value to a variable.
atomic_and(3C) These functions provide an atomic logical 'and' of a value to a variable.
atomic_bits(3C) These functions provide atomic bit setting and clearing within a variable.
atomic_cas(3C) These functions provide an atomic comparison of a value with a variable. If the comparison is equal, then swap in a new
value for the variable, returning the old value of the variable in either case.
atomic_dec(3C) These functions provide an atomic decrement on a variable.
atomic_inc(3C) These functions provide an atomic increment on a variable.
atomic_or(3C) These functions provide an atomic logical 'or' of a value to a variable.
atomic_swap(3C) These functions provide an atomic swap of a value with a variable, returning the old value of the variable.

NOTES
Atomic instructions ensure global visibility of atomically-modified variables on completion. In a relaxed store order system, this does
not guarantee that the visibility of other variables will be synchronized with the completion of the atomic instruction. If such synchro-
nization is required, memory barrier instructions must be used. See membar_ops(3C).
Atomic instructions can be expensive. since they require synchronization to occur at a hardware level. This means they should be used with
care to ensure that forcing hardware level synchronization occurs a minimum number of times. For example, if you have several variables
that need to be incremented as a group, and each needs to be done atomically, then do so with a mutex lock protecting all of them being
incremented rather than using the atomic_inc(3C) operation on each of them.
