16       const void *workload, size_t workload_size, char *job_handle)
17

DESCRIPTION

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

RETURN VALUE

47       gearman_return_t
