### Macros

    #include "boost/concept/assert.hpp"

    BOOST_CONCEPT_ASSERT((concept checking class template specialization));

Effects: causes a compilation failure if the concept is not satisfied.
Note: this macro can be used at global, class, or function scope.

    #include "boost/concept/requires.hpp"

    template <…template parameters…>
    BOOST_CONCEPT_REQUIRES(
      ((concept checking class template specialization1))
      ((concept checking class template specialization2))…
      ((concept checking class template specializationn)),
      (function return type)
    ) function_template_name(…function parameters…)

Effects: causes a compilation failure if the given concepts are not satisfied.
Note: this macro is intended to be used in place of a function template's return type.

    UNDER CONSTRUCTION

### Deprecated Functions

    #include "boost/concept_check.hpp"

    template <class Concept>
    void function_requires();

### Deprecated Macros

    #include "boost/concept_check.hpp"

    // Apply concept checks in class definitions.
    BOOST_CLASS_REQUIRE(type, namespace-of-concept, concept);
    BOOST_CLASS_REQUIRE2(type1, type2, namespace-of-concept, concept);
    BOOST_CLASS_REQUIRE3(type1, type2, type3, namespace-of-concept, concept);

    BOOST_CLASS_REQUIRES(type, concept);
    BOOST_CLASS_REQUIRES2(type1, type2, concept);
    BOOST_CLASS_REQUIRES3(type1, type2, type3, concept);
    BOOST_CLASS_REQUIRES4(type1, type2, type3, type4, concept);

### Deprecated Concept Checking Classes

For each of the concepts documented here, the library includes an identical concept checking class whose name ends in “`Concept`” For example, in addition to `RandomAccessIterator`, the library defines a `RandomAccessIteratorConcept` class template.
