Typedef Documentation

Cleanup_app_handler_T

typedef int(* Cleanup_app_handler_T) (void *, int, int)

Layout of an application provided cleanup function using an application provided handle as first argument and the signal number as second argument. The third argument is a flag bit field with no defined bits yet. If the handler returns 2 or -2 then it has delegated exit() to some other instance and the Cleanup handler shall return rather than exit.
