Macro Definition Documentation

◆ ATOMIC_INIT

#define ATOMIC_INIT (   i)    (i)

Definition at line 14 of file atomic.h.

◆ atomic_read

#define atomic_read (   v)    ((v)->counter)

atomic_read - read atomic variable @v: pointer of type atomic_t

Atomically reads the value of @v. Note that the guaranteed useful range of an atomic_t is only 24 bits.

Definition at line 23 of file atomic.h.

◆ atomic_set

#define atomic_set (   v,
  i 
)    InterlockedExchange((PLONG)(&(v)->counter), (LONG)(i))

atomic_set - set atomic variable @v: pointer of type atomic_t @i: required value

Atomically sets the value of @v to @i. Note that the guaranteed useful range of an atomic_t is only 24 bits.
