Function Documentation

__STATIC_INLINE void nrf_bitmask_bit_clear	(	uint32_t	bit,
		void *	p_mask
	)

Function for clearing a bit in the multi-byte bit mask.

Parameters

[in]	bit	Bit index.
[in]	p_mask	Pointer to mask with bit fields.

__STATIC_INLINE uint32_t nrf_bitmask_bit_is_set	(	uint32_t	bit,
		void const *	p_mask
	)

Function for checking if bit in the multi-byte bit mask is set.

Parameters

[in]	bit	Bit index.
[in]	p_mask	Pointer to mask with bit fields.

Returns

0 if bit is not set, positive value otherwise.

__STATIC_INLINE void nrf_bitmask_bit_set	(	uint32_t	bit,
		void *	p_mask
	)

Function for setting a bit in the multi-byte bit mask.

Parameters

[in]	bit	Bit index.
[in]	p_mask	Pointer to mask with bit fields.

__STATIC_INLINE void nrf_bitmask_masks_and	(	void const *	p_mask1,
		void const *	p_mask2,
		void *	p_out_mask,
		uint32_t	length
	)

Function for performing bitwise AND operation on two multi-byte bit masks.

Parameters

[in]	p_mask1	Pointer to the first bit mask.
[in]	p_mask2	Pointer to the second bit mask.
[in]	p_out_mask	Pointer to the output bit mask.
[in]	length	Length of output mask in bytes.

__STATIC_INLINE void nrf_bitmask_masks_or	(	void const *	p_mask1,
		void const *	p_mask2,
		void *	p_out_mask,
		uint32_t	length
	)

Function for performing bitwise OR operation on two multi-byte bit masks.

Parameters

[in]	p_mask1	Pointer to the first bit mask.
[in]	p_mask2	Pointer to the second bit mask.
[in]	p_out_mask	Pointer to the output bit mask.
[in]	length	Length of output mask in bytes.
