std::current_exception
| Defined in header <exception>
|
||
| std::exception_ptr current_exception() |
(since C++11) | |
If called during exception handling (typically, in a Template:cpp clause), captures the current exception object and creates an Template:cpp that holds a reference to that exception object, or to a copy of that exception object (it is implementation-defined if a copy is made)
If the implementation of this function requires a call to Template:cpp and the call fails, the returned pointer will hold a reference to an instance of Template:cpp
If the implementation of this function requires to copy the captured exception object and its copy constructor throws an exception, the returned pointer will hold a reference to the exception thrown. If the copy constructor of the thrown exception object also throws, the returned pointer may hold a reference to an instance of Template:cpp to break the endless loop.
If the function is called when no exception is being handled, an empty Template:cpp is returned.
