 # const_mem_fun1_t Class
 
-An adapter class that allows a **const** member function that takes a single argument to be called as a binary function object when initialized with a pointer argument.
+An adapter class that allows a **const** member function that takes a single argument to be called as a binary function object when initialized with a pointer argument. Deprecated in C++11, removed in C++17.
 
 ## Syntax
 
 ```cpp
 template <class Result, class Type, class Arg>
 class const_mem_fun1_t : public binary_function<const Type *, Arg, Result>
 {
-    explicit const_mem_fun1_t(Result (Type::* _Pm)(Arg) const);
-    Result operator()(const Type* _Pleft, Arg right) const;
+    explicit const_mem_fun1_t(Result (Type::* member_ptr)(Arg) const);
+    Result operator()(const Type* left, Arg right) const;
 };
 ```
 
 ### Parameters
 
-*_Pm*<br/>
+*member_ptr*<br/>
 A pointer to the member function of class `Type` to be converted to a function object.
 
-*_Pleft*<br/>
-The **const** object that the *_Pm* member function is called on.
+*left*<br/>
+The **const** object that the *member_ptr* member function is called on.
 
 *right*<br/>
-The argument that is being given to *_Pm*.
+The argument that is being given to *member_ptr*.
 
 ## Return Value
 
 An adaptable binary function.
 
 ## Remarks
 
-The template class stores a copy of *_Pm*, which must be a pointer to a member function of class `Type`, in a private member object. It defines its member function `operator()` as returning ( *_Pleft*->\*<em>Pm</em>)( *right* ) **const**.
+The template class stores a copy of *member_ptr*, which must be a pointer to a member function of class `Type`, in a private member object. It defines its member function `operator()` as returning `(left->member_ptr)(right) const`.
 
 ## Example
 
-The constructor of `const_mem_fun1_t` is not usually used directly; the helper function `mem_fun` is used to adapt member functions. See [mem_fun](../standard-library/functional-functions.md#mem_fun) for an example of how to use member function adaptors.
