Yes, they are.

Before I go too far down the wrong path, it has occurred to me that I
probably can't allow the lines to go out of scope?

ie, this (pseudocode) won't work

for each lineName in lineList
    temp_line = gpiod_chip_find_line(chip, lineName)
    gpiod_line_bulk_add(&bulk, temp_line);
next

As each line in the bulk will actually point to the same (last found) line?
Or am I missing a subtlety?
