Hi!

I've got a little problem which I cannot figure out how to solve. I have
a _Rreadk which I use to check if there is a record with a specified key
in the database. It's quite normal that there is no record with this
key, but if there is the program will do some additional processing.
I've run into a problem lately where the program misses that there is
this specific record; I believe it has to do with the way I use to check
the I/O-operation. Now I use:

rfb = _Rreadk ((*OQH)->koca2, (*OQH)->bufKOCA2, sizeof (RCA_t),
__KEY_EQ|__NO_LOCK, (*OQH)->keyKOCA2, sizeof(RCA2_k)); if
(rfb->num_bytes != sizeof(RCA_t)) {
        /* do something */
}

But what happens if the record does exist but it's locked? Now I have no
way to figure out why the _Rreadk failed. I've been looking at the
XXIOFB.h feedback mechanism but I don't find any useful, same with
errno. In the __XXIOFB_T there is a file_dep_fb_offset which I suppose
contain error code and reason code, but I cannot find any description of
what this pointer is pointing at.

I suppose some of you know how to solve this and perhaps have a
description of the file dependent feedback area.
