#141812 - Interesting example ... Responding to: ???'s previous message |
... on the pitfalls of asynchronously modified variables. Especially since it is probably hard to protect the variable by disabling interrupts when it is used in a switch-statement. Where would you disable and enable the interrupts there without accidentially "protecting" the whole switch statement ?
I would use a local copy of Ralph in this case. |
