Defined in header <exception>
template< class E > std::exception_ptr make_exception_ptr( E e ) noexcept;		(since C++11)

Creates an std::exception_ptr that holds a reference to a copy of e. This is done as if executing the following code:

try
{
    throw e;
}
catch(...)
{
    return std::current_exception();
}

Parameters

e

-

exception object to create a reference to the copy of

Return value

An instance of std::exception_ptr holding a reference to the copy of e, or to an instance of std::bad_alloc or to an instance of std::bad_exception (see std::current_exception).

Notes

The parameter is passed by value and is subject to slicing.
