well I can't, i am running my program on a server that I have no access to...:-( any more help? -
have you ever tried? I do not see any problem that you can't. You may use the network socket for sure for this in C++. One of them is listening on a specific port and the other one send messages to that port... as long as you have not both threads listening on same port things should be fine I suppose.Leave a comment:

how to return a 2-D array
Guys,
I have a private 2-D array and I am wondering how I can have a getArray() function to return it.
private:
string myarr[10][20];
I need the snippet of the code of the getArray() function! I checked all of the ways I know but none works...
Thank you in advance,

Is this OK?
I have a segmentation fault, and I am looking for it!
I am wondering if it is OK to do that:
may I do that or not?Code:class A{ public: B* myfunc(...); } void func(A * arg) B* test=new B(); test= arg->myfunc(...); .... }
I usually use memcpy... -
The problem is solved by these changes:
42. EventInterface: :EventInterface (callBackFunc * ptToFunc){
19. callBackFunc* receiveTest;
20. receiveTest->onMessageFunct ion=&myProgramT est::onMess;
55. onMessageFunc= *(callBackFunc* ) arg;
46. if (pthread_create ( &receiveThre ad, NULL, EventInterface: :receiveEvent, (void *) ptToFunc))
54. callBackFunc...Leave a comment:

callback confusion!
I am so confused... do you have any idea how I can come over this segmentation fault?
[CODE=cpp]
class myProgramTest : public EventInterface
{
public:
void myMainProg (void);
static void onMess(Event*, int);
private:
static int subscriptionID2 , subscriptionID, subscriptionID1 ;
};
void myProgramTest:: onMess(Event* _event, int subID){

This pointer qustion!
Guys,
As you know static member functions do not have a this pointer. so instead, what shall i do?
for example ... consider I want to call
and it is called in an static method so instead of this what can I put??Code:pthread_create(&thID,NULL,classA::B, (void *) this);
Thanks,

bitset<length> myBinary ((long) <your number>) ;

for those who might see this thread then... I finally come up with a syntax which WORKS!
I just wrap my pointer to function in an struct!\
...Code:class EventInterface { public: typedef struct{ void (*onMessageFunction)(Event*, int); } callBackFunc; EventInterface(callBackFunc); ... static void * receiveEvent (voidLeave a comment:

actually I read that after I post my new post!
The problem is the name of call back function is called from EventInterface constructor. so how could it be possible with your solution?!
maybe I need to read your solution more accurately....Leave a comment:

I guess I find a way to solve the problem.
...Code:class EventInterface { public: typedef void (*onMessageFunction)(Event*, int); EventInterface(onMessageFunction); } EventInterface::EventInterface(onMessageFunction pt2Func){ pthread_create( &receiveThread, NULL, EventInterface::receiveEvent,Leave a comment:

forexample when I define this like:
pthread_create( &receiveThre ad, NULL, EventInterface: :receiveEvent, (void *) (*ptToFunc))
or
pthread_create( &receiveThre ad, NULL, EventInterface: :receiveEvent, (void *) ptToFunc)
I have this error:
error: invalid conversion from 'void* (*)(void (*)(Event*, int))' to 'void* (*)(void*)'Leave a comment:
