* What really happens behind the scenes of those new
|
|
||||||
* __try{...}__except(..){....} and
|
|
||||||
* __try{...}__finally{...}
|
|
||||||
* statements is simply not documented by Microsoft. There could be different
|
|
||||||
* reasons for this:
|
|
||||||
* One reason could be that they try to hide the fact that exception
|
|
||||||
* handling in Win32 looks almost the same as in OS/2 2.x.
|
|
||||||
* Another reason could be that Microsoft does not want others to write
|
|
||||||
* binary compatible implementations of the Win32 API (like us).
|
|
||||||
*
|
|
||||||
* Whatever the reason, THIS SUCKS!! Ensuring portability or future
|
|
||||||
* compatibility may be valid reasons to keep some things undocumented.
|
|
||||||
* But exception handling is so basic to Win32 that it should be
|
|
||||||
* documented!
