__C_specific_handler function

Called by the compiler to implement structured exception handling extensions.

The relative address of the language specific handler is present in the UNWIND_INFO whenever flags UNW_FLAG_EHANDLER or UNW_FLAG_UHANDLER are set. The language specific handler is called as part of the search for an exception handler or as part of an unwind. For more information see Language Specific Handler.
