- rtemsInterrupt class.
-
- This class catches an interrupt and passes control to the user's
- derived class throught the handler method.
-
- The interrupt is released back to the previous handler when this
- object destructs.
-
- The old handler can be chained to after the interrupt is
- caught. Watch the stack usage!
-
- More than one instance of this class can catch the same vector. The
- application will have to chain to the other objects if required. If
- the old handler is not an instance of this class the chain is passed
- as "void (*)(void)". If it is an instance of this class, the handler
- method is directly called.
-
- The isr catch extends the documented return codes with :
-
- RTEMS_RESOURCE_IN_USE = interrupt already caught
