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 opera‐
       tions

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);

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.

CONTEXT
       These functions can be called from user, interrupt, or kernel context.
