-
- this is a little tricky since it should be portable.
-
- the openVMS/AXP object file has 'variable length' which means that
- read() returns data in chunks of (hopefully) correct and expected
- size. The linker (and other tools on vms) depend on that. Unix doesn't
- know about 'formatted' files, so reading and writing such an object
- file in a unix environment is not trivial.
-
- With the tool 'file' (available on all vms ftp sites), one
- can view and change the attributes of a file. Changing from
- 'variable length' to 'fixed length, 512 bytes' reveals the
- record length at the first 2 bytes of every record. The same
- happens during the transfer of object files from vms to unix,
- at least with ucx, dec's implementation of tcp/ip.
-
- The EVAX format repeats the length at bytes 2 & 3 of every record.
-
- On the first call (file_format == FF_UNKNOWN) we check if
- the first and the third byte pair (!) of the record match.
- If they do it's an object file in an unix environment or with
- wrong attributes (FF_FOREIGN), else we should be in a vms
- environment where read() returns the record size (FF_NATIVE).
-
- reading is always done in 2 steps.
- first just the record header is read and the length extracted
- by get_header_values
- then the read buffer is adjusted and the remaining bytes are
- read in.
