Boost bind what is 1

By default, the bind f, a1, a2, Functions that use a different calling convention , or variable-argument functions such as std::printf , do not work. On some platforms, extern "C" functions, like std::strcmp , are not recognized by the short form of bind. Some compilers, including MSVC 6. On MSVC up to version 7. Workaround: either use the qualified name, boost::bind , or use an using directive instead:.

Unfortunately, some libraries contain nested class templates named bind ironically, such code is often an MSVC specific workaround. MSVC up to version 7. Therefore, it will accept the incorrect in the current implementation form:. All unspecified-N types returned by bind are CopyConstructible. All unspecified-placeholder-N types are CopyConstructible. Their copy constructors do not throw exceptions. Throws: Nothing unless the copy constructors of F or A1 throw an exception.

Throws: Nothing unless the copy constructors of F , A1 or A2 throw an exception. Throws: Nothing unless the copy constructors of A1 or A2 throw an exception.

Implementations are allowed to provide additional bind overloads in order to support more arguments or different function pointer variations. This implementation supports function objects with up to nine arguments. Troubleshooting Incorrect number of arguments The function object cannot be called with the specified arguments Accessing an argument that does not exist Inappropriate use of bind f , Using bind with functions and function pointers.

Using bind with function objects. Using bind with pointers to members. Using nested binds for function composition. Overloaded operators new in Boost 1. Using bind with standard algorithms. Using bind with Boost.

Frequently Asked Questions. Why doesn't this compile? Incorrect number of arguments. The function object cannot be called with the specified arguments. Accessing an argument that does not exist. Inappropriate use of bind f , Binding a nonstandard function. Binding an overloaded function. Modeling STL function object concepts. MSVC specific: using boost :: bind ;.

MSVC specific: class templates shadow function templates. MSVC specific Common requirements. Common definitions. Throws: Nothing unless the copy constructor of F throws an exception. Throws: Nothing. Throws: Nothing unless the copy constructors of F or A1 throw an exception. Throws: Nothing unless the copy constructor of A1 throws an exception. Throws: Nothing unless the copy constructors of F , A1 or A2 throw an exception.

Throws: Nothing unless the copy constructors of A1 or A2 throw an exception. Additional overloads. Number of Arguments.

It uses the algorithm std::sort , which expects a binary function as its third parameter. The algorithm std::sort calls this binary function object with two values from the container v and evaluates the return value to sort the container.

The function compare is defined to sort v in descending order. Since compare is a binary function, it can be passed to std::sort directly. However, it can still make sense to use boost::bind because it lets you change the order of the parameters. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
