See vlib_buffer_advance(...). Depending on what you want to do - which you
didn’t share - that may be all you need.
In any event, these buffer metadata fields are involved:
current_data, current_length, total_length_not_including_first_buffer,
next_buffer, flags
Take a careful look at .../src/vlib/{buffer.h,buffer_funcs.h} to see usage
patterns.
