SYNOPSIS

#include <atomic.h>

void atomic_and_8(volatile uint8_t *target, uint8_t bits);

void atomic_and_uchar(volatile uchar_t *target, uchar_t bits);

void atomic_and_16(volatile uint16_t *target, uint16_t bits);

void atomic_and_ushort(volatile ushort_t *target, ushort_t bits);

void atomic_and_32(volatile uint32_t *target, uint32_t bits);

void atomic_and_uint(volatile uint_t *target, uint_t bits);

void atomic_and_ulong(volatile ulong_t *target, ulong_t bits);

void atomic_and_64(volatile uint64_t *target, uint64_t bits);

uint8_t atomic_and_8_nv(volatile uint8_t *target, uint8_t bits);

uchar_t atomic_and_uchar_nv(volatile uchar_t *target, uchar_t bits);

uint16_t atomic_and_16_nv(volatile uint16_t *target, uint16_t bits);

ushort_t atomic_and_ushort_nv(volatile ushort_t *target, ushort_t bits);

uint32_t atomic_and_32_nv(volatile uint32_t *target, uint32_t bits);

uint_t atomic_and_uint_nv(volatile uint_t *target, uint_t bits);

ulong_t atomic_and_ulong_nv(volatile ulong_t *target, ulong_t bits);

uint64_t atomic_and_64_nv(volatile uint64_t *target, uint64_t bits);

DESCRIPTION

These functions enable the the bitwise AND of bits to the value stored in target to occur in an atomic manner.  

RETURN VALUES

The *_nv() variants of these functions return the new value of target.  

ERRORS

No errors are defined.  

ATTRIBUTES

See attributes(5) for descriptions of the following attributes:

NOTES

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.
