In a recent reply here, I posted some code that used fwrite() to write
binary data to a file. One version of this code used mmap() to access
this binary data in-situ, and I wonder if I should have called fflush()
before calling mmap().

Yes.

Whether the data is buffered or not, is independent of whether the data is
text or not.
