# std::experimental::atomic_shared_ptr<T>::operator=

From cppreference.com
< cpp‎ | experimental‎ | atomic shared ptr

void operator=( shared_ptr<T> desired ) noexcept; | (1) |
void operator=( const atomic_shared_ptr& ) = delete; | (2) |

1) Atomically assigns a value `desired` to the atomic variable. Equivalent to store(desired).
2) Atomic variables are not CopyAssignable.

### Parameters

desired | - | value to assign

### Notes

Unlike most assignment operators, the assignment operators for `atomic_shared_ptr` returns void.

### Remarks

All changes to the `atomic_shared_ptr` object itself, and all associated `use_count` increments, are guaranteed to be performed atomically. Associated `use_count` decrements take place after the atomic operation, but are not required to be part of it. Any associated destruction or deallocation operations take place after the atomic operation and are not part of it.
