Signaler - interrupt handling
The Signaler
class enables the API programmer to register
functions that are to be called when the client application receives an
interrupt signal. The Signaler
class maintains a list of
registered functions and calls each one in turn.
By default, after all of the registered functions have been executed, the process exits, returning -1 to the operating system.
