                            scala.Function0<Object> action)

Adds an action to be run when a given signal is received by this process.

Note that signals are only supported on unix-like operating systems and work on a best-effort basis: if a signal is not available or cannot be intercepted, only a warning is emitted.

All actions for a given signal are run in a separate thread.

Parameters:

action - (undocumented)
