Why does the definiton of SWITCH_ADD_AP has a for(;;;) looping in it?

#define SWITCH_ADD_API(api_int, int_name, descript, funcptr, syntax_string) \

for (;;) { \

api_int = (switch_api_interface_t *)switch_loadable_module_create_interface(*module_interface, SWITCH_API_INTERFACE); \

api_int->interface_name = int_name; \

api_int->desc = descript; \

api_int->function = funcptr; \

api_int->syntax = syntax_string; \

break; \

}
