# Method Function.call_callback()

Method call_callback

  `void call_callback(function(:void) f, mixed ... args)`

Description

  Call a callback function, but send throws from the callback function (ie, errors) to master()->handle_error. Also accepts if f is zero (0) without error.

Example

  Functions.call_callback(the_callback,some,arguments);

equals

    {
          mixed err=catch { if (the_callback) the_callback(some,arguments); };
          if (err) master()->handle_error(err);
       }

(Approximately, since call_callback also calls handle_error if 0 were thrown.)
