|
|
If the file didn't already exist, we created it earlier. But we just
|
|
deleted it, which we still had to do in case we are overwriting an exis-
|
|
ting file. So we must create it now, again, to set the creation time
|
|
properly. (The creation time is the best functional approximation of
|
|
the Unix mtime. Really!)
|
|
|
|
If we stored this with an AOS/VS Zip that set the extra field to contain
|
|
the ?FSTAT packet and the ACL, we should use info from the ?FSTAT call
|
|
now. Otherwise (or if that fails), we should create anyway as best we
|
|
can from the normal Zip info.
|
|
|
|
In theory, we should look through an entire series of extra fields that
|
|
might exist for the same file, but we're not going to bother. If we set
|
|
up other types of extra fields, or if other environments we run into may
|
|
add their own stuff to existing entries in Zip files, we'll have to.
|
|
|
|
Note that all the packet types for sys_fstat() are the same size & mostly
|
|
have the same structure, with some fields being unused, etc. Ditto for
|
|
sys_create(). Thus, we assume a normal one here, not a dir/cpd or device
|
|
or IPC file, & make little adjustments as necessary. We will set ACLs
|
|
later (to reduce the chance of lacking access to what we create now); note
|
|
that for links the resolution name should be stored in the ACL field (once
|
|
we get Zip recognizing links OK).

Jan 1, 1968 through Dec 31, 2099. I have tested these
|
|
functions through the same range with exact agreement.
|
|
For dates outside of that range, the DG system calls
|
|
may return different values than these functions.
|
|
|
|
2. dgundate() accepts values between 0 and 48213 inclusive.
|
|
These correspond to 12/31/1967 and 12/31/2099.
|
|
|
|
3. Both functions assume the data is in the native OS byte
|
|
order. So if you're reading or writing these fields from
|
|
a file that has been passed between AOS/VS and PC-DOS you
|
|
will need to swap byte order.
|
|
|
|
4. With reference to byte order, the entire range of values
|
|
supported by these functions will fit into an unsigned
|
|
short int. In most cases the input or output will be
|
|
in that variable type. You are better off casting the
|
|
value to/from unsigned short so you only need to concern
|
|
yourself with swapping two bytes instead of four.
