[Freeswitch-dev] Need help on switch_ivr_originate(...) in switch_ivr_originate.c

[Alex To]

Hi,

 

Would somebody enlighten me on this trunk of code in the mentioned file at
line 2273:

 

if (local_clobber) {

                              if (var_event) {

                                    switch_event_t *event;

                                    switch_event_header_t *header;

                                    /* install the vars from the {} params
*/

                                    for (header = var_event->headers;
header; header = header->next) {

 
switch_channel_set_variable(originate_status[i].peer_channel, header->name,
header->value);

                                    }

                                    switch_event_create(&event,
SWITCH_EVENT_CHANNEL_ORIGINATE);

                                    switch_assert(event);

 
switch_channel_event_set_data(originate_status[i].peer_channel, event);

                                    switch_event_fire(&event);

                              }

                        }

 

                        if (vdata) {

                              char *var_array[1024] = { 0 };

                              int var_count = 0;

                              if ((var_count = switch_separate_string(vdata,
'|', var_array, (sizeof(var_array) / sizeof(var_array[0]))))) {

                                    int x = 0;

                                    for (x = 0; x < var_count; x++) {

                                          char *inner_var_array[2] = { 0 };

                                          int inner_var_count;

                                          if ((inner_var_count =

 
switch_separate_string(var_array[x], '=',

 
inner_var_array, (sizeof(inner_var_array) / sizeof(inner_var_array[0])))) ==
2) {

 

 
switch_channel_set_variable(originate_status[i].peer_channel,
inner_var_array[0], inner_var_array[1]);

                                          }

                                    }

                              }

                        }

 

                        if (!local_clobber) {

                              if (var_event) {

                                    switch_event_t *event;

                                    switch_event_header_t *header;

                                    /* install the vars from the {} params
*/

                                    for (header = var_event->headers;
header; header = header->next) {

 
switch_channel_set_variable(originate_status[i].peer_channel, header->name,
header->value);

                                    }

                                    switch_event_create(&event,
SWITCH_EVENT_CHANNEL_ORIGINATE);

                                    switch_assert(event);

 
switch_channel_event_set_data(originate_status[i].peer_channel, event);

                                    switch_event_fire(&event);

                              }

                        }

 

The code block inside if (local_clobber) and if (!local_clobber) does
exactly the same thing. May I know is it by design and how does it actually
work ? I am not sure what does it mean by localClobber so if someone can
spare sometime explaining, I would really appreciate it.

 

Thank you

 

Best Regards
