On this Linux system, "man 7 unix", in the section "SCM_RIGHTS", it
explains how the passing mechanism is handled.  One paragraph reads:
 
              Commonly, this operation is referred to as "passing  a

              accurately, what is being passed is a reference to  an
              open  file  description  (see open(2)), and in the re‐
              ceiving process it is likely that a different file de‐
              scriptor  number will be used.

Note the distinction between “file description” (the in-kernel data
structure that stores the context about the open file), and “file
descriptor” (the userland reference to the file description).
