C++ Boostboost::function Frequently Asked Questions

Q: I see void pointers; is this [mess] type safe?

Yes, boost::function is type safe even though it uses void pointers and pointers to functions returning void and taking no arguments. Essentially, all type information is encoded in the functions that manage and invoke function pointers and function objects. Only these functions are instantiated with the exact type that is pointed to by the void pointer or pointer to void function. The reason that both are required is that one may cast between void pointers and object pointers safely or between different types of function pointers (provided you don't invoke a function pointer with the wrong type). @@ -21,7 +21,7 @@ void g() { return f(); }

This is a valid usage of boost::function because void returns are not used.

C++ BoostBoost.Function Tutorial

 
 
 Boost.Function has two syntactical forms: the preferred form and the compatibility form. The preferred form fits more closely with the C++ language and reduces the number of separate template parameters that need to be considered, often improving readability; however, the preferred form is not supported on all platforms due to compiler bugs. The compatible form will work on all compilers supported by Boost.Function. Consult the table below to determine which syntactic form to use for your compiler.

    Basic Usage
    
 
     A function wrapper is defined simply by instantiating the function class template with the desired return type and argument types, formulated as a C++ function type. Any number of arguments may be supplied, up to some implementation-defined limit (10 is the default maximum). The following declares a function object wrapper f that takes two int parameters and returns a float:

 the implicit conversions would have been applied to the arguments without any user interference. The only limit on the types of arguments is that they be CopyConstructible, so we can even use references and arrays:

     The header <boost/function.hpp> includes a family of class templates that are function object wrappers. The notion is similar to a generalized callback. It shares features with function pointers in that both define a call interface (e.g., a function taking two integer arguments and returning a floating-point value) through which some implementation can be called, and the implementation that is invoked may change throughout the course of the program.

    Compatibility Note
    
 
     Boost.Function has been partially redesigned to minimize the interface and make it cleaner. Several seldom- or never-used features of the older Boost.Function have been deprecated and will be removed in the near future. Here is a list of features that have been deprecated, the likely impact of the deprecations, and how to adjust your code:
