# Dynamically loading each of the Service Objects below causes a # number of threads to be spawned, each one invoking the Service # Configurator (e.g. ACE_Service_Config::process_directive(). If the # Service Configurator is thread safe and reentrant, then parsing of # this `Service_Config_Test.conf' file should run to completion # without error. # # Test_Object_1 will cause Test_Object_2 and Test_Object_3 to be # dynamically loaded. Dynamic loading of each of object will occur in # a separate thread. dynamic Test_Object_1 Service_Object * Service_Config_DLL:_make_Service_Config_DLL() "2 3" // 引号内是参数 # Test_Object_4 will cause Test_Object_5 and Test_Object_6 to be # dynamically loaded.
