[Boost-users] boost bind question, can it create a functor with more arguments than needed

Dear all,

Probably this is something one does not encounter often, but I have here an 
interface which expects more arguments than needed, e.g.:

void SomeInterface(boost::function<void (Arg1, Arg2)> fcCallback)
{}

now I have another functor like:
boost::function<void (Arg1)> fc;

I want fc apply to SomeInterface, and it only needs to fill in argument1.

So I need something like boost::bind(fc, _1, _2) to get it compilable for 
SomeInterface, only bind now thinks that fc has a prototype of two 
arguments. Is there a way to tell bind to ignore argument2 (without explicit 
write a functor)?

wkr,
me
