The GEMDOS Fread(), etc are more similar to the UNIX read(), etc,
NOT fread(), etc.  The raw GEMDOS functions are faster (due to
no buffering) but you should set up your own buffering.  (I found out
that a 9Kbyte buffer is good enough for almost-maximum floppy-disk
performance.)  If you want to write code so that it is easy to port
to UNIX and such, write read(), etc calls in the UNIX syntax, and
set up a bunch of routines with those names that simply translate
to the GEMDOS calls.   (BEWARE of int-vs-long problems!)
