Returns a copy of the allocator object associated with the multiset.
Member type allocator_type is the type of the allocator used by the container, defined in multiset as an alias of its third template parameter (Alloc).
The example shows an elaborate way to allocate memory for an array of ints using the same allocator used by the container.
Output:
Concurrently accessing the elements of a multiset is safe.
Copying any instantiation of the default allocator is also guaranteed to never throw.

Get allocator
Parameters
noneReturn Value
The allocator.Member type allocator_type is the type of the allocator used by the container, defined in multiset as an alias of its third template parameter (Alloc).
Example
|
|
Output:
The allocated array contains: 10 20 30 40 50 |
Complexity
Constant.Iterator validity
No changes.Data races
The container is accessed.Concurrently accessing the elements of a multiset is safe.
Exception safety
No-throw guarantee: this member function never throws exceptions.Copying any instantiation of the default allocator is also guaranteed to never throw.
