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