atomic_bits(9F) 					   Kernel Functions for Drivers 					   atomic_bits(9F)

NAME

       atomic_bits, atomic_set_long_excl, atomic_clear_long_excl - atomic set and clear bit operations

SYNOPSIS

       #include <sys/atomic.h>

       int atomic_set_long_excl(volatile ulong_t *target, uint_t bit);

       int atomic_clear_long_excl(volatile ulong_t *target, uint_t bit);

DESCRIPTION

       The  atomic_set_long_excl()  and  atomic_clear_long_excl()  functions perform an exclusive atomic bit set or clear operation on target. The
       value of bit specifies the number of the bit to be modified within target. Bits are numbered from zero to one less than the maximum  number
       of bits in a long. If the value of bit falls outside of this range, the result of the operation is undefined.

RETURN VALUES

       The  atomic_set_long_excl()  and  atomic_clear_long_excl() functions return 0 if bit was successfully set or cleared. They return -1 if bit
       was already set or cleared.

ERRORS

       No errors are defined.

CONTEXT

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

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.
