710
711 This is a little tricky since it should be portable.
712
713 The openVMS object file has 'variable length' which means that
714 read() returns data in chunks of (hopefully) correct and expected
715 size. The linker (and other tools on VMS) depend on that. Unix
716 doesn't know about 'formatted' files, so reading and writing such
717 an object file in a Unix environment is not trivial.
718
719 With the tool 'file' (available on all VMS FTP sites), one
720 can view and change the attributes of a file. Changing from
721 'variable length' to 'fixed length, 512 bytes' reveals the
722 record size at the first 2 bytes of every record. The same
723 may happen during the transfer of object files from VMS to Unix,
724 at least with UCX, the DEC implementation of TCP/IP.
725
726 The VMS format repeats the size at bytes 2 & 3 of every record.
727
728 On the first call (file_format == FF_UNKNOWN) we check if
729 the first and the third byte pair (!) of the record match.
730 If they do it's an object file in an Unix environment or with
731 wrong attributes (FF_FOREIGN), else we should be in a VMS
732 environment where read() returns the record size (FF_NATIVE).
733
734 Reading is always done in 2 steps:
735 1. first just the record header is read and the size extracted,
736 2. then the read buffer is adjusted and the remaining bytes are
737 read in.
738
