DESCRIPTION

       A  gearman_task_st represents a task.  Work that is sent by a client to a gearman server is seen as a task (a worker recieves a task in the
       form of a job.

       Tasks, i.e. gearman_task_st are created by calling either gearman_execute(),  gearman_client_add_task(),  or  gearman_client_add_task_back-
       ground().

       gearman_client_add_task_status() can also create gearman_task_st, these tasks will be used to monitor a previously created gearman_task_st.

       gearman_task_free()  is	used to free a task. This only needs to be done if a task was created with a preallocated structure or if you want
       to clean up the memory of a specific task.

       gearman_task_set_context() sets the given context of the gearman_task_st. The context can be used to pass information to a gearman_task_st.

       gearman_task_context()  returns	the  context  that  was  used  in  the	creation  of  the  gearman_task_st   (or   that   was	set   with
       gearman_task_set_context().

       gearman_task_data()  returns  the  current  data that has been returned to the task. gearman_task_data_size() will give you the size of the
       value. gearman_task_take_data() is the same as gearman_task_data() but the value that is returned must be freed by  the	client	(free(3)).
       gearman_task_recv_data() can be used with pre-allocated buffers.

       gearman_task_is_known(),  gearman_task_is_running(), gearman_task_numerator(), and gearman_task_denominator(), return values related to the
       last status update that was made to the gearman_task_st. They do not cause the gearman_task_st to update itself.

       gearman_task_error() return the last error message that the  gearman_task_st  encountered.  gearman_task_return()  return  the  last  gear-
       man_return_t  stored.  A  value	of GEARMAN_UNKNOWN_STATE means that the task has not been submitted to server yet, or that no function was
       available if the job has been submitted.

RETURN VALUE

       Various. Values that are returned by gearman_task_take_data() must have free(3) called on them.
