Re: QDMRTVFO API won't work - help

Mark,

I haven't used this particular API, but I see two problems with your code:

1: The first parameter for the API is (most probably) the receiver variable
for the information you want.  You supply RTRNOVRDATA, so that is where the
API puts the information (take a look at it after the call).  In fact, you
want to pass data structure OVRL0100 as the first parameter (and have
parameter LENGTH have the length of this DS).  BTW: the name of the DS can
be anything; the format parameter of the API, 'OVRL0100', only specifies the
layout of the information you get.

2: Like others pointed out: BYTPRV in the error parameter DS should contain
the length of the DS.  This is where you tell the API the maximum length of
error it may return.
