735
736 This is a little tricky since it should be portable.
737
738 The openVMS object file has 'variable length' which means that
739 read() returns data in chunks of (hopefully) correct and expected
740 size. The linker (and other tools on VMS) depend on that. Unix
741 doesn't know about 'formatted' files, so reading and writing such
742 an object file in a Unix environment is not trivial.
743
744 With the tool 'file' (available on all VMS FTP sites), one
745 can view and change the attributes of a file. Changing from
746 'variable length' to 'fixed length, 512 bytes' reveals the
747 record size at the first 2 bytes of every record. The same
748 may happen during the transfer of object files from VMS to Unix,
749 at least with UCX, the DEC implementation of TCP/IP.
750
751 The VMS format repeats the size at bytes 2 & 3 of every record.
752
753 On the first call (file_format == FF_UNKNOWN) we check if
754 the first and the third byte pair (!) of the record match.
755 If they do it's an object file in an Unix environment or with
756 wrong attributes (FF_FOREIGN), else we should be in a VMS
757 environment where read() returns the record size (FF_NATIVE).
758
759 Reading is always done in 2 steps:
760 1. first just the record header is read and the size extracted,
761 2. then the read buffer is adjusted and the remaining bytes are
762 read in.
