NAME
       atomic_cas,	atomic_cas_8,	  atomic_cas_uchar,	atomic_cas_16,
       atomic_cas_ushort,  atomic_cas_32,  atomic_cas_uint,  atomic_cas_ulong,
       atomic_cas_64, atomic_cas_ptr - atomic compare and swap operations

SYNOPSIS
       #include <atomic.h>

       uint8_t	atomic_cas_8(volatile  uint8_t	*target,  uint8_t cmp, uint8_t
       newval);

       uchar_t atomic_cas_uchar(volatile uchar_t *target, uchar_t cmp, uchar_t
       newval);

       uint16_t	  atomic_cas_16(volatile   uint16_t   *target,	uint16_t  cmp,
       uint16_t newval);

       ushort_t atomic_cas_ushort(volatile  ushort_t  *target,	ushort_t  cmp,
       ushort_t newval);

       uint32_t	  atomic_cas_32(volatile   uint32_t   *target,	uint32_t  cmp,
       uint32_t newval);

       uint_t atomic_cas_uint(volatile uint_t *target, uint_t cmp, uint_t new‐
       val);

       ulong_t atomic_cas_ulong(volatile ulong_t *target, ulong_t cmp, ulong_t
       newval);

       uint64_t	 atomic_cas_64(volatile	 uint64_t   *target,   uint64_t	  cmp,
       uint64_t newval);

       void *atomic_cas_ptr(volatile void *target, void *cmp, void *newval);

DESCRIPTION
       These  functions	 enable	 a  compare and swap operation to occur atomi‐
       cally. The value stored in target is compared with cmp. If these values
       are  equal, the value stored in target is replaced with newval. The old
       value stored in target is returned by the function whether or  not  the
       replacement occurred.

RETURN VALUES
       These functions return the old of *target.

ERRORS
       No errors are defined.
