DESCRIPTION

       Callbacks for client execution task states.

       gearman_client_set_data_fn()  sets  the callback function that will be called if server is
       to make a request to the client to provide more data.

       gearman_client_do_job_handle() gest the job handle for the running task.  This  should  be
       used between repeated gearman_client_do() (and related) calls to get information.

       gearman_client_clear_fn() can be called to remove all existing gearman_actions_t that have
       been set.

       gearman_client_set_created_fn(),                             gearman_client_set_data_fn(),
       gearman_client_set_warning_fn(),                           gearman_client_set_status_fn(),
       gearman_client_set_complete_fn(),          gearman_client_set_exception_fn(),          and
       gearman_client_set_fail_fn(), set callback functions for the different states of execution
       for a client request. Each request, ie a creation of  gearman_task_st,  keeps  a  copy  of
       callbacks when it is created.

       gearman_client_set_exception_fn()  will  only  be  called if exceptions are enabled on the
       server. You can do this by calling gearman_client_set_server_option().

       An example of this:

          const char *EXCEPTIONS="exceptions";
          gearman_client_set_server_option(client, EXCEPTIONS, strlen(EXCEPTIONS));

RETURN VALUE

       None
