ATOMIC_DEFINE [1/2]

#define ATOMIC_DEFINE	(		name,
			num_bits
	)		atomic_t name[1 + ((num_bits) - 1) / ATOMIC_BITS]

Define an array of atomic variables.

This macro defines an array of atomic variables containing at least num_bits bits.

Note

If used from file scope, the bits of the array are initialized to zero; if used from within a function, the bits are left uninitialized.

Parameters

name	Name of array of atomic variables.
num_bits	Number of bits needed.

ATOMIC_DEFINE [2/2]

#define ATOMIC_DEFINE	(		name,
			num_bits
	)		atomic_t name[1 + ((num_bits) - 1) / ATOMIC_BITS]

Define an array of atomic variables.

This macro defines an array of atomic variables containing at least num_bits bits.

Note

If used from file scope, the bits of the array are initialized to zero; if used from within a function, the bits are left uninitialized.

Parameters

name	Name of array of atomic variables.
num_bits	Number of bits needed.
