Bitmask module
- group nrf_bitmask
Bitmask managing module.
Defines
-
BITMASK_BYTES_CALCULATE(bits_count)
Get number of bytes needed to store the given bitmask.
- Parameters
bits_count – [in] Number of bits in the bitmask.
- Returns
Number of bytes to store requested bit mask.
-
BITMASK_BYTE_GET(abs_bit)
Macro for getting index of byte in byte stream where
abs_bitis put.
-
BITMASK_RELBIT_GET(abs_bit)
Macro for getting relative index of bit in byte.
Functions
-
__STATIC_INLINE bool 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
bit – [in] Bit index.
p_mask – [in] Pointer to mask with bit fields.
- Return values
true – If the specified bit is set.
false – If the specified bit is cleared.
-
__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
bit – [in] Bit index.
p_mask – [inout] Pointer to mask with bit fields.
-
__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
bit – [in] Bit index.
p_mask – [inout] Pointer to mask with bit fields.
-
__STATIC_INLINE void nrf_bitmask_masks_or(void const *p_mask1, void const *p_mask2, void *p_out_mask, size_t length)
Function for performing bitwise OR operation on two multi-byte bit masks.
- Parameters
p_mask1 – [in] Pointer to the first bit mask.
p_mask2 – [in] Pointer to the second bit mask.
p_out_mask – [out] Pointer to the output bit mask.
length – [in] Length of output mask in bytes.
-
__STATIC_INLINE void nrf_bitmask_masks_and(void const *p_mask1, void const *p_mask2, void *p_out_mask, size_t length)
Function for performing bitwise AND operation on two multi-byte bit masks.
- Parameters
p_mask1 – [in] Pointer to the first bit mask.
p_mask2 – [in] Pointer to the second bit mask.
p_out_mask – [out] Pointer to the output bit mask.
length – [in] Length of output mask in bytes.
