Package paladin provides simple protection of critical resources against asynchronous interruption signals sent by the operating systems. Paladin provides a Run method that expects
-
a function to obtain a resource
-
a function to release the resource
-
and a function that is run in between obtaining and releasing the resource; the user application should entirely live within this function.
Currently, only SIGINT is handled and the behaviour is to close the program. More sophisticated behaviour and more signals will be provided in the future.
