Questions tagged [boost-bind]

boost::bind is a generalization of the standard C++ functions std::bind1st and std::bind2nd. It supports arbitrary function objects, functions, function pointers, and member function pointers, and is able to bind any argument to a specific value or route input arguments into arbitrary positions.

boost::bind is a generalization of the standard C++ functions std::bind1st and std::bind2nd. It supports arbitrary function objects, functions, function pointers, and member function pointers, and is able to bind any argument to a specific value or route input arguments into arbitrary positions. bind does not place any requirements on the function object; in particular, it does not need the result_type, first_argument_type and second_argument_type standard typedefs.

boost::bind was proposed for standardization and a version of it was included in as std::tr1::bind and an improved version is included in the standard as std::bind (see ).

solving issue # C++98 Valid use of “for_each” in the code using Boost library 1.53 or 1.56

I already asked the question. I am wondering if there is any solution for this using boost::for_each and boost::bind. The question has been already answered, that's why I created another issue here; only for the curiosity. Thanks.

boost bind or lambda functor that returns a constant

Can I use boost::bind or the boost lambda library to create a functor that ignores its arguments and always returns a constant? e.g. a functor with equivalent behaviour to: int returnThree( SomeType arg ) { return 3; }
