Exception(3) Exception(3)NAME Class Exception: Object -- manage a stack of exception handlersSYNOPSIS Object Exception new(Exception()); int catch (self) void cause (int number)DESCRIPTION Exception is a class for managing a stack of exception handlers. After it is armed with catch, the newest Excep- tion object can receive a nonzero exception number sent with cause(). ctor pushes the new Exception object onto the global exception stack, dtor removes it. These calls must be balanced. catch arms its object for receiving an exception number. Once the number is sent, catch will return it. This func- tion is implemented as a macro with setjmp(3) and is sub- ject to the same restrictions; in particular, the function containing the call to catch must still be active when the exception number is sent. Other methods should generally not be applied to an Excep- tion object.SEE ALSO setjmp(3) local: ats 1
