'frankly' is the definition.
(thesaurus)

'position void' is the wordplay.
'position' becomes 'point' (I can't explain this - if you can you should give a lot more credence to this answer).
'void' becomes 'blank' (I've seen this before).
'point'+'blank'='POINT-BLANK'

Can you help me to learn more?

(Another definition for point-blank that I've seen is " Abrupt, direct".)

I've seen this clue in The Telegraph.
