| 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. |
| 762 | |
