|

* \brief A Win32 structured exception handler that throws C++ exceptions.
|
||||
*
|
||||
* This class can only be used on Microsoft Windows platforms. On the rest of
|
||||
* supported platforms, including this header file from compilable code raises
|
||||
* a compiler error.
|
||||
*
|
||||
* For this handler to work properly, all code that may raise asynchronous
|
||||
* (structured) exceptions must be compiled with the '-EHa' Visual C/C++
|
||||
* compiler option. Otherwise no asynchronous exception thrown in a try{} block
|
||||
* will be caught by the corresponding catch{} block, and the program will
|
||||
* terminate.
