You're right ... from the Tcl perspective, getting a tempfile
that you can't id by name is useless.  Populating is OK:

set fd [file mkstemp $template]
set dllInKit /path/to/vfs/lib.dll
set fdDll [open $dllInKit]
chan configure $fd -encoding binary
chan configure $fdDll -encoding binary
chan copy $fdDll $fd
chan close $fd
chan close $fdDll

but then you can't 'load' it ...
