NAME

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

SYNOPSIS

       #include <libgearman/gearman.h>

       gearman_priority_t

       gearman_return_t       gearman_client_do_background(gearman_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(gearman_client_st *client,     const
       char *function_name,   const  char *unique,  const  void *workload,  size_t workload_size,
       gearman_job_handle_t job_handle)

       gearman_return_t     gearman_client_do_low_background(gearman_client_st *client,     const
       char *function_name,   const  char *unique,  const  void *workload,  size_t workload_size,
       gearman_job_handle_t job_handle)

DESCRIPTION

       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.

RETURN VALUE

       gearman_return_t
