This function takes two bit patterns of equal length and performs the logical AND operation on each pair of corresponding bits. If the bits at the same position are both 1, then the result is 1; otherwise, the result is 0. If either input argument is NULL, the function returns NULL.

If the target_arg and bit_mask_arg arguments differ in length, the arguments are processed as follows:

  • The target_arg and bit_mask_arg arguments are aligned on their least significant byte/bit.
  • The smaller argument is padded with zeros to the left until it becomes the same size as the larger argument.
