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.
