Function sys_bitarray_find_nth_set 

pub unsafe extern "C" fn sys_bitarray_find_nth_set(

Find nth bit set in region

This counts the number of bits set (@p count) in a region (@p offset, @p num_bits) and returns the index (@p found_at) of the nth set bit, if it exists, as long with a zero return value.

If it does not exist, @p found_at is not updated and the method returns

@param[in] bitarray Bitarray struct @param[in] n Nth bit set to look for @param[in] num_bits Number of bits to check, must be larger than 0 @param[in] offset Starting bit position @param[out] found_at Index of the nth bit set, if found

@retval 0 Operation successful @retval 1 Nth bit set was not found in region @retval -EINVAL Invalid argument (e.g. out-of-bounds access, trying to count 0 bits, etc.)
