DESCRIPTION

       gearman_worker_st is used for worker communication with the server.

       gearman_worker_context()   and  gearman_worker_set_context()  can  be  used  to  store  an
       arbitrary object for the user.

       gearman_worker_set_task_context_free_fn() sets a  trigger  that  will  be  called  when  a
       gearman_task_st is released.

       gearman_worker_timeout()  and gearman_worker_set_timeout() get and set the current timeout
       value, in milliseconds, for the worker.

       gearman_worker_function_exist() is used to determine if a  given  worker  has  a  specific
       function.

       gearman_worker_work() have the worker execute against jobs until an error occurs.

       gearman_worker_grab_job()   Takes   a  job  from  one  of  the  job  servers.  It  is  the
       responsibility of the caller to free the job once they are done. This interface is used in
       testing, and is very rarely the correct interface to program against.

       Normally   malloc(3)  and  free(3)  are  used  for  allocation  and  releasing  workloads.
       gearman_worker_set_workload_malloc_fn() and gearman_worker_set_workload_free_fn()  can  be
       used to replace these with custom functions.

       If   you   need   to   remove   a   function   from   the   server  you  can  call  either
       gearman_worker_unregister_all() to remove all functions  that  the  worker  has  told  the
       gearmand  server about, or you can use gearman_worker_unregister() to remove just a single
       function.
