GEARMAN_CLIENT_DO_HIGH_BACKGROUND(3GearmanGEARMAN_CLIENT_DO_HIGH_BACKGROUND(3)NAMEgearman_client_do_high_background - Gearmand Documentation,
http://gearman.info/
SYNOPSIS
#include <libgearman/gearman.h>
gearman_priority_t
gearman_return_t gearman_client_do_background(gear‐
man_client_st *client, const char *function_name, const char *unique,
const void *workload, size_t workload_size, char *job_handle)
Changed in version 0.21: GEARMAN_PAUSE will no longer be returned. A do
operation will now run until it has been submitted.
gearman_return_t gearman_client_do_high_background(gear‐
man_client_st *client, const char *function_name, const char *unique,
const void *workload, size_t workload_size, gearman_job_han‐
dle_t job_handle)
gearman_return_t gearman_client_do_low_background(gear‐
man_client_st *client, const char *function_name, const char *unique,
const void *workload, size_t workload_size, gearman_job_han‐
dle_t job_handle)
DESCRIPTIONgearman_client_do_background() executes a single request to the gear‐
mand server and returns the status via gearman_return_t.
gearman_client_add_task_high_background() and gear‐
man_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.
RETURN VALUE
gearman_return_t
