Implementation principle of try/catch-go

Turn: implementation principle of try/catch

1. Try/catch of VC ++ is implemented based on Win32 Seh.

2. Try/catch can only catch exceptions of the current thread. Each thread has its own exception handling entry.

3. The exception handling portal is called by the OS when an exception occurs.

4. To use Seh, the VC ++ compiler automatically generates a lot of code.
