That sounds like a reasonable guess.

FreeBSD's `ftruncate' man page says:

  DESCRIPTION
       Truncate() causes the file named by path or referenced by fd to
       be truncated or extended to length bytes in size.  If the file
       was larger than this size, the extra data is lost.  If the file
       was smaller than this size, it will be extended as if by
       writing bytes with the value zero.  With ftruncate(), the file
       must be open for writing.

  RETURN VALUES
       A value of 0 is returned if the call succeeds.  If the call
       fails a -1 is returned, and the global variable errno specifies
       the error.

Is that different from what you expected?  If not, is there a test
program that I could run that would test for the behavior that you
expect?
