atomic_swap(9F) Kernel Functions for Drivers atomic_swap(9F) 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. ATTRIBUTES
