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 <sys/atomic.h>

       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);

       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.

       These functions return the old of *target.

       No errors are defined.

       These functions can be called from user or interrupt context.
