Macro Definition Documentation

atomic_dec

#define atomic_dec

(

v

)

(((v)->counter)--)

atomic_dec - decrement atomic variable

Parameters

v	pointer of type atomic_t

Atomically decrements v by 1. Note that the guaranteed useful range of an atomic_t is only 24 bits.

Definition at line 50 of file atomic.h.

atomic_inc

#define atomic_inc

(

v

)

(((v)->counter)++)

atomic_inc - increment atomic variable

Parameters

v	pointer of type atomic_t

Atomically increments v by 1. Note that the guaranteed useful range of an atomic_t is only 24 bits.

Definition at line 41 of file atomic.h.

ATOMIC_INIT

#define ATOMIC_INIT

(

i

)

{ (i) }

Definition at line 9 of file atomic.h.

atomic_read

#define atomic_read

(

v

)

((v)->counter)

atomic_read - read atomic variable

Parameters

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 22 of file atomic.h.

atomic_set

#define atomic_set	(		v,
			i
	)		(((v)->counter) = (i))

atomic_set - set atomic variable

Parameters

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.
