Read contained value (explicit memory order)
Parameters
- obj
- Pointer to an atomic object.
Type A represents other overloaded atomic types (if the library does not implement the C-style atomic types as instantiations of atomic).
- sync
- Synchronization mode for the operation.
This shall be one of the following values of the enum type memory_order:
Return value
The contained value.
T is the type of the contained value (atomic's template parameter).
Data races
No data races (atomic operation). Memory order specified by argument sync.
Exception safety
No-throw guarantee: never throws exceptions.
