693
694 This is a little tricky since it should be portable.
695
696 The openVMS object file has 'variable length' which means that
697 read() returns data in chunks of (hopefully) correct and expected
698 size. The linker (and other tools on VMS) depend on that. Unix
699 doesn't know about 'formatted' files, so reading and writing such
700 an object file in a Unix environment is not trivial.
701
702 With the tool 'file' (available on all VMS FTP sites), one
703 can view and change the attributes of a file. Changing from
704 'variable length' to 'fixed length, 512 bytes' reveals the
705 record size at the first 2 bytes of every record. The same
706 may happen during the transfer of object files from VMS to Unix,
707 at least with UCX, the DEC implementation of TCP/IP.
708
709 The VMS format repeats the size at bytes 2 & 3 of every record.
710
711 On the first call (file_format == FF_UNKNOWN) we check if
712 the first and the third byte pair (!) of the record match.
713 If they do it's an object file in an Unix environment or with
714 wrong attributes (FF_FOREIGN), else we should be in a VMS
715 environment where read() returns the record size (FF_NATIVE).
716
717 Reading is always done in 2 steps:
718 1. first just the record header is read and the size extracted,
719 2. then the read buffer is adjusted and the remaining bytes are
720 read in.
721
