I took a moment to dig into the BPX interface for this, I found BPX1PWD,
which documents __passwd(). It also documents __passwd_applid(),
but provides no interface information for it (although it discusses it
as if it were a different interface) and provides alternatives to using
the __passwd_applid BPX interface if you wanted to set fields in the BPX
thread info yourself.
Seems like there is some doc confusion there...
I didn't find a separate BPX offset definition for __passwd_applid().
Is the _only_ way to specify the APPLID via directly setting fields in
the BPXYTHLI
thread-info or is there an actual BPX-level interface for this?
