GEARMAN_CLIENT_DO_BACKGROUND(3) Gearmand GEARMAN_CLIENT_DO_BACKGROUND(3)

gearman_client_do_background - Gearmand Documentation, http://gearman.info/

#include <libgearman/gearman.h>



Changed in version 0.21: GEARMAN_PAUSE will no longer be returned. A do operation will now run until it has been submitted.



gearman_client_do_background() executes a single request to the gearmand server and returns the status via gearman_return_t.

gearman_client_add_task_high_background() and gearman_client_add_task_low_background() are identical to gearman_client_do_background(), only they set the gearman_priority_t to either high or low.

If job_handle is not NULL, it will be populated with the name of the job_handle for the task created. The job handle needs to be the size of GEARMAN_JOB_HANDLE_SIZE. Please see gearman_job_handle_t for more information.
