ATOMIC_AND(3)		 BSD Library Functions Manual		 ATOMIC_AND(3)

NAME
     atomic_and, atomic_and_32, atomic_and_uint, atomic_and_ulong,
     atomic_and_64, atomic_and_32_nv, atomic_and_uint_nv, atomic_and_ulong_nv,
     atomic_and_64_nv — atomic logical ‘and’ operations

SYNOPSIS
     #include <sys/atomic.h>

     void
     atomic_and_32(volatile uint32_t *ptr, uint32_t bits);

     void
     atomic_and_uint(volatile unsigned int *ptr, unsigned int bits);

     void
     atomic_and_ulong(volatile unsigned long *ptr, unsigned long bits);

     void
     atomic_and_64(volatile uint64_t *ptr, uint64_t bits);

     uint32_t
     atomic_and_32_nv(volatile uint32_t *ptr, uint32_t bits);

     unsigned int
     atomic_and_uint_nv(volatile unsigned int *ptr, unsigned int bits);

     unsigned long
     atomic_and_ulong_nv(volatile unsigned long *ptr, unsigned long bits);

     uint64_t
     atomic_and_64_nv(volatile uint64_t *ptr, uint64_t bits);

DESCRIPTION
     The atomic_and family of functions load the value of the variable refer‐
     enced by ptr, perform a logical ‘and’ with the value bits, and store the
     result back to the variable referenced by ptr in an atomic fashion.

     The *_nv() variants of these functions return the new value.

     The 64-bit variants of these functions are available only on platforms
     that can support atomic 64-bit memory access.  Applications can check for
     the availability of 64-bit atomic memory operations by testing if the
     pre-processor macro __HAVE_ATOMIC64_OPS is defined.

SEE ALSO
     atomic_ops(3)

HISTORY
     The atomic_and functions first appeared in NetBSD 5.0.
