Subject: pop_retr(): Add a `void *closure' to be passed to action callback.
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/d3d8f636ed951b4c02bdeeb146b528fe00dfbb48?hp=d3d8f636ed951b4c02bdeeb146b528fe00dfbb48

pop_retr(): Add a `void *closure' to be passed to action callback.

Only caller passes in NULL for the moment, and doesn't use it in the
callback, but it will allow fewer scopes by name of the variables the
action callback uses.
