No, it isn't!  It is returned.

The problem is that it isn't documented.  It needs to be described in
two places:
1. <cbm.h>,
2. the function reference document.

cbm_readdir() returns a result code.  When that code is 0, struct
cbm_dirent contains valid data in _all_ of its members.  But, when that
code is 2, the structure still has valid data!  The size member has the
number of "free" blocks on the disk (IDEDOS gives the sum of the
displayed file sizes).  [CBM-Command uses that cbm_readdir() feature.]

P.S., it's the /* Size in 254B blocks */, not 256.
