Standard C Library Functions atomic_swap(3C)
NAME
atomic_swap, atomic_swap_8, atomic_swap_uchar,
atomic_swap_16, atomic_swap_ushort, atomic_swap_32,
atomic_swap_uint, atomic_swap_ulong, atomic_swap_64,
atomic_swap_ptr - atomic swap operations
SYNOPSIS
#include
uint8_t atomic_swap_8(volatile uint8_t *target, uint8_t newval);
uchar_t atomic_swap_uchar(volatile uchar_t *target, uchar_t newval);
uint16_t atomic_swap_16(volatile uint16_t *target, uint16_t newval);
ushort_t atomic_swap_ushort(volatile ushort_t *target, ushort_t newval);
uint32_t atomic_swap_32(volatile uint32_t *target, uint32_t newval);
uint_t atomic_swap_uint(volatile uint_t *target, uint_t newval);
ulong_t atomic_swap_ulong(volatile ulong_t *target, ulong_t newval);
uint64_t atomic_swap_64(volatile uint64_t *target, uint64_t newval);
void *atomic_swap_ptr(volatile void *target, void *newval);
DESCRIPTION
These functions enable a swap operation to occur atomically. The value stored in target is replaced with newval. The old value is returned by the function.RETURN VALUES
These functions return the old of *target.ERRORS
No errors are defined.ATTRIBUTES
