734
735 This is a little tricky since it should be portable.
736
737 The openVMS object file has 'variable length' which means that
738 read() returns data in chunks of (hopefully) correct and expected
739 size. The linker (and other tools on VMS) depend on that. Unix
740 doesn't know about 'formatted' files, so reading and writing such
741 an object file in a Unix environment is not trivial.
742
743 With the tool 'file' (available on all VMS FTP sites), one
744 can view and change the attributes of a file. Changing from
745 'variable length' to 'fixed length, 512 bytes' reveals the
746 record size at the first 2 bytes of every record. The same
747 may happen during the transfer of object files from VMS to Unix,
748 at least with UCX, the DEC implementation of TCP/IP.
749
750 The VMS format repeats the size at bytes 2 & 3 of every record.
751
752 On the first call (file_format == FF_UNKNOWN) we check if
753 the first and the third byte pair (!) of the record match.
754 If they do it's an object file in an Unix environment or with
755 wrong attributes (FF_FOREIGN), else we should be in a VMS
756 environment where read() returns the record size (FF_NATIVE).
757
758 Reading is always done in 2 steps:
759 1. first just the record header is read and the size extracted,
760 2. then the read buffer is adjusted and the remaining bytes are
761 read in.
