下面我附上代码：

sscanf(serv_class_ID + 2, "%X", &num);
class = num;
//printf("Service Class 0x%X\n", class);
}
if (class) {
if (class & 0xffff0000){
sdp_uuid32_create(&svc_uuid, class);

}
else {

}
}

// connect to the SDP server running on the remote machine

case SDP_UUID16:
case SDP_UUID32:
case SDP_UUID128:

break;
case SDP_UINT8:

//printf("rfcomm channel: %d\n",d->val.int8);
}
turn_d = d->val.int8;
printf("%d---1",turn_d); //----------------------输出为3
break;
}
}
}
sdp_list_free( (sdp_list_t*)p->data, 0 );
}
sdp_list_free( proto_list, 0 );
}
//printf("found service record 0x%x\n", rec->handle);
sdp_record_free( rec );
}
sdp_close(session);
printf("%d----2\n",turn_d); //----------------------输出为25
return turn_d;
}
int main()
{
int i;
char bdaddr[]="00:15:83:B9:78:A6";
i=sdp_channel(bdaddr);
printf("--%d--\n",i); //-------------------------输出为25
}
运行结果：
3------1
25-----2
--25--
请高手指点是哪出错了啊，急啊！！！
