695
696 This is a little tricky since it should be portable.
697
698 The openVMS object file has 'variable length' which means that
699 read() returns data in chunks of (hopefully) correct and expected
700 size. The linker (and other tools on VMS) depend on that. Unix
701 doesn't know about 'formatted' files, so reading and writing such
702 an object file in a Unix environment is not trivial.
703
704 With the tool 'file' (available on all VMS FTP sites), one
705 can view and change the attributes of a file. Changing from
706 'variable length' to 'fixed length, 512 bytes' reveals the
707 record size at the first 2 bytes of every record. The same
708 may happen during the transfer of object files from VMS to Unix,
709 at least with UCX, the DEC implementation of TCP/IP.
710
711 The VMS format repeats the size at bytes 2 & 3 of every record.
712
713 On the first call (file_format == FF_UNKNOWN) we check if
714 the first and the third byte pair (!) of the record match.
715 If they do it's an object file in an Unix environment or with
716 wrong attributes (FF_FOREIGN), else we should be in a VMS
717 environment where read() returns the record size (FF_NATIVE).
718
719 Reading is always done in 2 steps:
720 1. first just the record header is read and the size extracted,
721 2. then the read buffer is adjusted and the remaining bytes are
722 read in.
723
