public member function

std::list::get_allocator

<list>
allocator_type get_allocator() const;
Get allocator
Returns the allocator object used to construct the container.

Parameters

none

Return Value

The allocator.

Member type allocator_type is defined to the same as the second template parameter used to instantitate this specific list class (its Allocator type).

// list::get_allocator
#include <iostream>
#include <list>

using namespace std;

int main ()
{
  list<int> mylist;
  int * p;
  unsigned int i;

  // allocate an array of 5 elements using mylist's allocator:
  p=mylist.get_allocator().allocate(5);

  // assign some values to array
  for (i=0; i<5; i++) p[i]=i;

  cout << "The allocated array contains:";
  for (i=0; i<5; i++) cout << " " << p[i];
  cout << endl;

  mylist.get_allocator().deallocate(p,5);

  return 0;
}

The example shows an elaborate way to allocate memory for an array of ints using the same allocator used by the container. Output:
The allocated array contains: 0 1 2 3 4

Complexity

Constant.
