std::pointer_to_unary_function is a function object that acts as a wrapper around a unary function.

Member functions

(constructor)
 constructs a new pointer_to_unary_function object with the supplied function
(public member function)
operator()
 calls the stored function
(public member function)

std::pointer_to_unary_function::pointer_to_unary_function

explicit pointer_to_unary_function( Result (*f)(Arg) );

Constructs a pointer_to_unary_function function object with the stored function f.

Parameters

f - pointer to a function to store

std::pointer_to_unary_function::operator()

Result operator()( Arg x ) const;

Calls the stored function.

Parameters

x - argument to pass to the function

Return value
