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_exe‐
cute(), 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 cre‐
ation 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.
RETURN VALUE
Various. Values that are returned by gearman_task_take_data() must have
free(3) called on them.
