Atomically loads and returns the current value of the atomic variable pointed to by
obj. The operation is atomic read operation.
The first version orders memory accesses according to memory_order_seq_cst, the second version orders memory accesses according to
order must be one of memory_order_relaxed, memory_order_consume, memory_order_acquire or memory_order_seq_cst. Otherwise the behavior is undefined.
This is a generic function defined for all atomic object types.
A is the type of an atomic object,
C is the non-atomic type corresponding to
|obj||-||pointer to the atomic object to access|
|order||-||the memory synchronization ordering for this operation|
The current value of the atomic variable pointed to by
