#include <atomic.h> void atomic_or_8(volatile uint8_t *target, uint8_t bits); void atomic_or_uchar(volatile uchar_t *target, uchar_t bits); void atomic_or_16(volatile uint16_t *target, uint16_t bits); void atomic_or_ushort(volatile ushort_t *target, ushort_t bits); void atomic_or_32(volatile uint32_t *target, uint32_t bits); void atomic_or_uint(volatile uint_t *target, uint_t bits); void atomic_or_ulong(volatile ulong_t *target, ulong_t bits); void atomic_or_64(volatile uint64_t *target, uint64_t bits); uint8_t atomic_or_8_nv(volatile uint8_t *target, uint8_t bits); uchar_t atomic_or_uchar_nv(volatile uchar_t *target, uchar_t bits); uint16_t atomic_or_16_nv(volatile uint16_t *target, uint16_t bits); ushort_t atomic_or_ushort_nv(volatile ushort_t *target, ushort_t bits); uint32_t atomic_or_32_nv(volatile uint32_t *target, uint32_t bits); uint_t atomic_or_uint_nv(volatile uint_t *target, uint_t bits); ulong_t atomic_or_ulong_nv(volatile ulong_t *target, ulong_t bits); uint64_t atomic_or_64_nv(volatile uint64_t *target, uint64_t bits); These functions enable the the bitwise OR of bits to the value stored in target to occur in an atomic manner. The *_nv() variants of these functions return the new value of target. No errors are defined. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Stable | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ atomic_add(3C), atomic_and(3C), atomic_bits(3C), atomic_cas(3C), atomic_dec(3C), atomic_inc(3C), atomic_swap(3C), membar_ops(3C), attributes(5), atomic_ops(9F) The *_nv() variants are substantially more expensive on some platforms than the versions that do not return values. Do not use them unless you need to know the new value atomically. 13 May 2005 atomic_or(3C)
