The C++11 function std::bind() fixes some or all arguments of a function object, returning another function object that takes fewer arguments.

std::bind performs Partial Function Application of arbitrary C++ function objects, fixing some or all arguments of a function object and returning another function object that takes fewer arguments.

The function is based on boost::bind() which originated in the library (see ) and an earlier version was included in as std::tr1::bind().

How to bind a member function to an object in C++14

I am trying to bind a member function to an object while keeping the arguments open. I know I can do it by wrapping it in a lambda expression (like this) but I want to use std::bind and std::placeholders to do it. So far this is what I've…

Is it possible to accept the output of `std::bind` directly as a value, without conversion to std::function?

This answer states that std::bind returns an object by value, and this comment implies that assigning to std::function will cause a heap allocation to store the value returned by std::bind. Is there a way to avoid this heap allocation and pass the…

Different overloads with std::function parameters is ambiguous with bind (sometimes)

I have two overloads of a function foo which take different std::functions which results in an ambiguity issue for the latter when used with the result of a std::bind. I don't understand why only this is ambiguous. void…

In C++11, is it possible to wrap a template function in a std::function?

If i have a template function in C++11, is it then possible to wrap it in a std::function? My problem is like this: I have a generic function (say a sum function) where the return type depends on the types of the arguments: template

Is it safe to change a function pointers signature and call it to ignore the return type?

In our codebase we have callbacks that are stored using (eg. std::function). Sometimes we would like to bind a function with a different signature to the callback which can be done using bind. This is fine for different function parameters…

How can I avoid this code duplication?

I have two methods which have almost the same code except for two methods they call (and some other details I can easily parameterize). However, those method calls have the same signature, so I think I can generalize them into a single method. class…

Parallel of std::reference_wrapper for std::shared_ptrs

If you want to bind a reference to a function f, you can use std::bind(f, std::ref(x)). In this case f takes a reference or makes a copy. Now I have a function void g(T & t). I would like to bind the input argument to std::shared_ptr mySharedPtr…
