16       *workload, size_t workload_size, char *job_handle)
17
18       Changed in version 0.21: GEARMAN_PAUSE will no longer be returned. A do
19       operation will now run until it has been submitted.

DESCRIPTION

31       gearman_client_do_background()  executes  a single request to the gear‐
32       mand server and returns the status via gearman_return_t.
33
34       gearman_client_add_task_high_background()           and           gear‐
35       man_client_add_task_low_background()       are       identical       to
36       gearman_client_do_background(), only they set the gearman_priority_t to
37       either high or low.
38
39       If  job_handle  is  not NULL, it will be populated with the name of the
40       job_handle for the task created. The job handle needs to be the size of
41       GEARMAN_JOB_HANDLE_SIZE.  Please  see gearman_job_handle_t for more in‐
42       formation.

RETURN VALUE

45       gearman_return_t
