SYNOPSIS

#include <atomic.h>

void atomic_inc_8(volatile uint8_t *target);

void atomic_inc_uchar(volatile uchar_t *target);

void atomic_inc_16(volatile uint16_t *target);

void atomic_inc_ushort(volatile ushort_t *target);

void atomic_inc_32(volatile uint32_t *target);

void atomic_inc_uint(volatile uint_t *target);

void atomic_inc_ulong(volatile ulong_t *target);

void atomic_inc_64(volatile uint64_t *target);

void atomic_inc_ptr(volatile void *target);

uint8_t atomic_inc_8_nv(volatile uint8_t *target);

uchar_t atomic_inc_uchar_nv(volatile uchar_t *target);

uint16_t atomic_inc_16_nv(volatile uint16_t *target);

ushort_t atomic_inc_ushort_nv(volatile ushort_t *target);

uint32_t atomic_inc_32_nv(volatile uint32_t *target);

uint_t atomic_inc_uint_nv(volatile uint_t *target);

ulong_t atomic_inc_ulong_nv(volatile ulong_t *target);

uint64_t atomic_inc_64_nv(volatile uint64_t *target);

void *atomic_inc_ptr_nv(volatile void *target);

DESCRIPTION

These functions enable the inrementing (by one) of 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.
