/* The following definitions allow using exceptions in Wine and Winelib code
*
* They should be used like this:
*
* __TRY
* {
* do some stuff that can raise an exception
* }
* __EXCEPT(filter_func)
* {
* handle the exception here
* }
* __ENDTRY
*
* or
*
* __TRY
* {
* do some stuff that can raise an exception
* }
* __FINALLY(finally_func)
*
* The filter_func and finally_func functions must be defined like this:
*
* LONG CALLBACK filter_func( PEXCEPTION_POINTERS __eptr ) { ... }
*
* void CALLBACK finally_func( BOOL __normal ) { ... }
*
* The filter function must return one of the EXCEPTION_* code; it can
* use GetExceptionInformation() and GetExceptionCode() to retrieve the
* exception info.
*
* Warning: Inside a __TRY or __EXCEPT block, 'break' or 'continue' statements
* break out of the current block, but avoid using them because they
* won't work when compiling with native exceptions. You cannot use
* 'return', 'goto', or 'longjmp' to leave a __TRY block either, as
* this will surely crash. You can use 'return', 'goto', or 'longjmp'
* to leave an __EXCEPT block though.
