## Unwinding

Unwinding uses exception tables to find the next point at which normal execution can occur, or fail if there are no exception handlers.
Unwinding uses exception tables to find the next point at which normal execution can occur, or fail if there are no exception handlers. For more information on what exception tables are, see [exception handling](exception_handling.md).
