Re: Struggling with API QDFRTVFD

I just did a Google search "QDFRTVFD site:ibm.com"

which returned a "C" example for the API
"This document contains an example of how to retrieving the Row/Column
of a Field Using the QDFRTVFD API."

Hi Jevgeni

How are things, hope all is well.
Did you manage to get the API working?

I have a RPG version coded here.
http://wiki.midrange.com/index.php/QDFRTVFD
The API is VERY BIG and my program only gets the basic info of
Fields/Constants and attributes.
But I am not doing so well in converting it to C.

Perhaps you have some suggestions.

Frank

Thought that "with a little help" from Mark and Carsten I solved my

problem.

How mistaken I've been...
I only need a list of fields with field name, I/O attribute, field type

and length.

Found field names in QDFFNTB structure. Very good. All other necessary

data was also available starting from there.

But then I found out, that hidden fields' names are missing in QDFFNTB

structure at all! Field is mentioned, I can retrieve all attributes - but
not the name...

Continued searching - as Carsten advised - went to QDFWFLEI and from
there

to QDFWRCDI and QDFFNTBL.

Very good again, now all names available, including hindden, also field

lengths.

But how to get data type and I/O? There is an index to QDFFFITB, but
I saw

that in my DSPF with 7 formats these indexes repeate. So they are unique
inside one format only. And I failed to find reference to format names in
Where-Used part of the puzzle...

The only idea I have by now is to rely on formats order and assume that

order of records in "Where-used" section matches exactly order of formats
in Record format table (QDFARFTE)

Or I am missing something again?
