737/* Get next record from object file to vms_buf.
738 Set PRIV(buf_size) and return it
739
740 This is a little tricky since it should be portable.
741
742 The openVMS object file has 'variable length' which means that
743 read() returns data in chunks of (hopefully) correct and expected
744 size. The linker (and other tools on VMS) depend on that. Unix
745 doesn't know about 'formatted' files, so reading and writing such
746 an object file in a Unix environment is not trivial.
747
748 With the tool 'file' (available on all VMS FTP sites), one
749 can view and change the attributes of a file. Changing from
750 'variable length' to 'fixed length, 512 bytes' reveals the
751 record size at the first 2 bytes of every record. The same
752 may happen during the transfer of object files from VMS to Unix,
753 at least with UCX, the DEC implementation of TCP/IP.
754
755 The VMS format repeats the size at bytes 2 & 3 of every record.
756
757 On the first call (file_format == FF_UNKNOWN) we check if
758 the first and the third byte pair (!) of the record match.
759 If they do it's an object file in an Unix environment or with
760 wrong attributes (FF_FOREIGN), else we should be in a VMS
761 environment where read() returns the record size (FF_NATIVE).
762
763 Reading is always done in 2 steps:
764 1. first just the record header is read and the size extracted,
765 2. then the read buffer is adjusted and the remaining bytes are
766 read in.
767
