Classes

bad_function_call	A class that describes an exception thrown to indicate that a call to operator() on a function object failed because the object was empty.
binary_negate	A template class providing a member function that negates the return value of a specified binary function.
binder1st	A template class providing a constructor that converts a binary function object into a unary function object by binding the first argument of the binary function to a specified value.
binder2nd	A template class providing a constructor that converts a binary function object into a unary function object by binding the second argument of the binary function to a specified value.
