DESCRIPTION

61       Callbacks for client execution task states.
62
63       gearman_client_set_data_fn() sets the callback function  that  will  be
64       called  if  server  is  to make a request to the client to provide more
65       data.
66
67       gearman_client_do_job_handle() gest the  job  handle  for  the  running
68       task. This should be used between repeated gearman_client_do() (and re‐
69       lated) calls to get information.
70
71       gearman_client_clear_fn()  can  be  called  to  remove   all   existing
72       gearman_actions_t that have been set.
73
74       gearman_client_set_created_fn(),          gearman_client_set_data_fn(),
75       gearman_client_set_warning_fn(),        gearman_client_set_status_fn(),
76       gearman_client_set_complete_fn(),    gearman_client_set_exception_fn(),
77       and gearman_client_set_fail_fn(), set callback functions for  the  dif‐
78       ferent  states  of  execution  for a client request. Each request, ie a
79       creation of gearman_task_st, keeps a copy of callbacks when it is  cre‐
80       ated.
81
82       gearman_client_set_exception_fn() will only be called if exceptions are
83       enabled  on  the  server.  You   can   do   this   by   calling   gear‐
84       man_client_set_server_option().
85
86       An example of this:
87
88          const char *EXCEPTIONS="exceptions";
89          gearman_client_set_server_option(client, EXCEPTIONS, strlen(EXCEPTIONS));
90

RETURN VALUE

92       None
