roll-pitch-yaw and heading-pitch-bank, difference?

Hi, I read in my 3D math book that “heading-pitch-bank” was also called “roll-pitch-yaw” with roll=bank and yaw=heading, but it is not very clear if the order of rotations (around y, x and z axes for heading-pitch-bank) was the same or not (z-x-y axes for roll-pitch-yaw? or same as heading-pitch-bank, heading/bank and roll/yaw words are just swapped?). Thank you.
