|

set PRIV(buf_size) and return it
|
||
|
||
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.
