This function takes two bit patterns of equal length and performs the logical OR operation on each pair of corresponding bits as follows.

IF... THEN the result is...
either of the bits from the input arguments is 1 1
both of the bits from the input arguments are 0 0
any of the input arguments is NULL 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.

For more information, see Performing Bit-Byte Operations against Arguments with Non-Equal Lengths.
