how to split function: bind

Question

I need to compile a bind function in a Posix embedded, and can't use boost::bind or std::bind.

So I want to split the function: threadReducer.reduce(boost::bind(&DepthMap::observeDepthRow, this, _1, _2, _3), 3, height-3, 10);

where the function observeDepthRow:
void DepthMap::observeDepthRow(int yMin, int yMax, RunningStats* stats)
and the function reduce:
void IndexThread::reduce(boost::function<void(int,int,RunningStats*)> callPerIndex, int first, int end, int stepSize = 0)

Plz, help me split the function, I am not good at C++

Why can't you use `boost::bind` (or `std::bind` for that matter)? Especially if you (apparently) can still continue to use `boost::function`? — Some programmer dude, Nov 23 '16 at 12:50
this is my previous code, I need change all. The function reduce, is click "follow symbol", and show the function. — nistar, Nov 23 '16 at 13:20

If you cannot use boost or c++11 .. in that in that case you may try like this :

void IndexThread::reduce(void(*function)(int,int,RunningStats*), int first, int end, int stepSize = 0)

and make your observeDepthRow static

static void DepthMap::observeDepthRow(int yMin, int yMax, RunningStats* stats)

Then you can call it like this :

threadReducer.reduce(observeDepthRow, 3, height-3, 10);

although in this case you will have to make your method static if you do not wish so do have look at this.
