NAME
atomic_add, atomic_add_32, atomic_add_int, atomic_add_long, atomic_add_ptr, atomic_add_64, atomic_add_32_nv, atomic_add_int_nv, atomic_add_long_nv, atomic_add_ptr_nv, atomic_add_64_nv -- atomic add operations SYNOPSIS
#include <sys/atomic.h> void atomic_add_32(volatile uint32_t *ptr, int32_t delta); void atomic_add_int(volatile unsigned int *ptr, int delta); void atomic_add_long(volatile unsigned long *ptr, long delta); void atomic_add_ptr(volatile void *ptr, ssize_t delta); void atomic_add_64(volatile uint64_t *ptr, int64_t delta); uint32_t atomic_add_32_nv(volatile uint32_t *ptr, int32_t delta); unsigned int atomic_add_int_nv(volatile unsigned int *ptr, int delta); unsigned long atomic_add_long_nv(volatile unsigned long *ptr, long delta); void * atomic_add_ptr_nv(volatile void *ptr, ssize_t delta); uint64_t atomic_add_64_nv(volatile uint64_t *ptr, int64_t delta); DESCRIPTION
The atomic_add family of functions add a signed value delta to the variable referenced by ptr in an atomic fashion. The *_nv() variants of these functions return the new value. The 64-bit variants of these functions are available only on platforms that can support atomic 64-bit memory access. Applications can check for the availability of 64-bit atomic memory operations by testing if the pre-processor macro __HAVE_ATOMIC64_OPS is defined. SEE ALSO
atomic_ops(3) HISTORY
The atomic_add functions first appeared in NetBSD 5.0. BSD
April 11, 2007 BSD
