416.0. "determining buffer quota of a mailbox?" by CSC32::J_HENSON (Don't get even, get ahead!) Thu Apr 03 1997 17:31

Can anyone tell me how to determine the buffer quota with which a mailbox
has been created?  According to the I/O User's Guide, $getdvi/dvi$_devbufsiz
returns the maximum message size.  Also, it appears that show dev/full
and sda>sho dev do the same.

Nothing I can find addresses determining the buffer quota.

Thanks,

Jerry

    SDA> EXAMINE UCB+UCB$W_INIQUO
    Take a look at the low word...
    The latter is probably what you want -- the requested quota.
    INIQUO is initialized for user mailboxes...

    re .1
    
    Is there a version of (VAX) VMS that allows a mailbox to have a buffer
    quota exceeding 65535 bytes? [Yes, customer could address this with
    better application design but...]

Nope ... that only works for you :-)

But if you'd care to make it available to the rest of us (perhaps via the
Freeware CD) I for one would be very happy to test it ...

    it will come in SYS$EXAMPLES:MBX$SDA.C in the next OpenVMS release
    (Raven) as part of the now becoming supported and documented SDA
    Extensions...

Will existing VAX SDA extensions continue to function?
