Reference Manual C API (Async / Callbacks)

• ex_wait()
  tells expecco, that although the execute() function will return, the action is still active, and that there will be a callback at some later time, which will report the outcome via success() / error() / fail().
  Use this if the action gets a callback from an asynchronous function or a separate thread. The callback function MUST then call one of the success() / inconclusive() / fail() or error() functions to signal completion to expecco.
  This should be the last statement/expression before the execute function returns.

Notice the different name: there is already a function called "wait()"in the c-library.
