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. | |
