    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);
    

     

    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.
