+   of every function that does an explicit write to stdout.  The last

+
+   FIXME: note the fflush suggested above is implicit in the fclose
+   we actually do below.  Consider doing only the fflush and/or using
+   setvbuf to inhibit buffering.
+
+   Besides, it's wasteful to check the return value from every call
+   that writes to stdout -- just let the internal stream state record
+   the failure.  That's what the ferror test is checking below.
