这个问题与:同一进程中是否可以有多个 ORB 对象?
因此,感谢@BrianKelly,我找到了有关ORB
标识符的信息(即使ORBACUS
我拥有的所有文档中都没有此类信息)并且我成功创建了一个简单的应用程序,它连接到不同的CORBA
服务器并成功执行了多个CORBA
请求。
到目前为止,一切都很好。
现在,我想做的是让这个应用程序成为多线程的,并启动一个单独的线程来连接到不同的服务器。但是ORB_init
崩溃。
这是一个非常短的代码,我用于测试:
#include <OB/CORBA.h>
pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;
void* run( void * );
struct config { const char* nameservice; const char* id; const char* exe; };
const bool mt = true;
int main()
{
config cfg1 = { "NameService=corbaloc::10.102.8.15:13069/NameService", "1", "test" };
config cfg2 = { "NameService=corbaloc::192.168.1.99:13069/NameService", "2", "test" };
if( mt )
{
pthread_t t1, t2;
pthread_create( &t1, NULL, run, (void*)&cfg1 );
pthread_create( &t2, NULL, run, (void*)&cfg2 );
pthread_join( t1, NULL ); pthread_join( t2, NULL );
}
else
{
run( (void*)&cfg1 );
run( (void*)&cfg2 );
}
printf( "SUCCESS!\n" );
return 0;
}
void* run( void* arg )
{
pthread_mutex_lock( &mutex );
int argc = 2; char* argv[3];
config* cfg = (config*)arg;
argv[0] = (char*)cfg->exe;
argv[1] = (char*)cfg->nameservice;
argv[2] = NULL;
CORBA::ORB_var m_varOrb = CORBA::ORB_init( argc, argv, cfg->id );
pthread_mutex_unlock( &mutex );
return NULL;
}
所以,什么时候,一切mt
都false
很好,我可以扩展代码来创建一些特定于服务器的对象,执行不同的请求等。但是mt
,true
第二个线程调用失败ORB_init
。请参阅下面的堆栈跟踪。
我很确定我错过了一些非常简单和愚蠢的东西,但是什么?
