    In text-mode, the elements read/written are characters;

      Notice that typical stdio's use a single errno global variable to return an error code,
claus
parents: 308
diff changeset
  1407
      this was bad design in the stdio lib (right from the very beginning), since its much
claus
parents: 308
diff changeset
  1408
      harder to deal with this in the presence of lightweight processes, where errno gets
claus
parents: 308
diff changeset
  1409
      overwritten by an I/O operation done in another thread. (stdio should have been written
claus
parents: 308
diff changeset
  1410
      to return errno as a negative number ...).
claus
parents: 308
diff changeset
  1411
      To deal with this, the scheduler treats errno like a per-thread private variable,
claus
parents: 308
diff changeset
  1412
      and saves/restores the errno setting when switching to another thread.

      (Notice that some thread packages do this also, but ST/X's thread implementation

      does not depend on those, but instead uses a portable private package).
