Set PRIV(buf_size) and return it

This is a little tricky since it should be portable.
|
||
|
||
The openVMS 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 size at the first 2 bytes of every record. The same
|
||
may happen during the transfer of object files from VMS to Unix,
|
||
at least with UCX, the DEC implementation of TCP/IP.
|
||
|
||
The VMS format repeats the size 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:
|
||
1. first just the record header is read and the size extracted,
|
||
2. then the read buffer is adjusted and the remaining bytes are
|
||
read in.
|
||
|
||
All file I/O is done on even file positions. */
