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 receives 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_background().

       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
       gearman_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.
