operator|| Operator

Creates a task that will complete successfully when either of the tasks supplied as arguments completes successfully.

template<
   typename _ReturnType
>
task<_ReturnType> operator||(
   const task<_ReturnType> & _Lhs,
   const task<_ReturnType> & _Rhs
);

template<
   typename _ReturnType
>
task<std::vector<_ReturnType>> operator||(
   const task<std::vector<_ReturnType>> & _Lhs,
   const task<_ReturnType> & _Rhs
);

template<
   typename _ReturnType
>
task<std::vector<_ReturnType>> operator||(
   const task<_ReturnType> & _Lhs,
   const task<std::vector<_ReturnType>> & _Rhs
);

inline task<void> operator||(
   const task<void> & _Lhs,
   const task<void> & _Rhs
);

_ReturnType

The type of the returned task.

_Lhs

The first task to combine into the resulting task.

_Rhs

The second task to combine into the resulting task.

A task that completes sucessfully when either of the input tasks has completed successfully. If the input tasks are of type T, the output of this function will be a task<std::vector<T>. If the input tasks are of type void the output task will also be a task<void>.

If both of the tasks are canceled or throw exceptions, the returned task will complete in the canceled state, and one of the exceptions, if any are encountered, will be thrown when you call get() or wait() on that task.
