WaitForMultipleObjects equivalent in linux

[shamjs]

Hi,All
im using WaitForMultipleObjects in windows,but my questions is how to do the same in linux since there is no equivalent api in linux.....
(since i need my threads to wait for the event to trigger)
Here is my code

long PredictThread(const Array2D<REAL> &X)  
	{
		if (X.dim2()!=m_NumVars) return -1;
		long i,j;
		
		Array3D<REAL> Ypred(X.dim1(),m_Categories.size(), 6, 0.0);
			
		HANDLE* TID = new HANDLE[m_Categories.size()];
		DWORD ThreadID;

		TParam* pOTParam = new TParam[m_Categories.size()];
		TParam* pTParam = pOTParam;
		for(j=0;j<m_Categories.size();++j)
		{
			TParam* pParam = pTParam;
			pParam->category = j;
			pParam->model = m_Categories[j];
			pParam->X = X.copy();
			pParam->Ypred = Ypred;

			TID[j] = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)ThreadProc,(LPVOID)pParam,0,&ThreadID);
			pTParam++;
		}
		WaitForMultipleObjects(m_Categories.size(), TID, TRUE, INFINITE);
		for(j=0;j<m_Categories.size();++j)
			CloseHandle(TID[j]);

		delete [] TID;
		delete [] pOTParam;
		m_members = Ypred;		
		return 0;
	}

please help in fixing this issue
thanking you ....................

Assuming you are using posix threads (pthreads), you may be able to use pthread_cond_wait() to simulate this Windows function. You should carefully read and understand the pthreads documentation before you continue. There is quite a bit of information in the man pages (see "man pthreads" and the man pages for other pthread functions and structures) which will help you use these api's.

Hi Shams
Just to augment what Rubberman passed on, if you want your code to be cross platform so one set of code compiles on both Linux and Windows, you can use this package on Windows:
POSIX Threads (pthreads) for Win32
I use it and it works pretty well. You can compile the library statically and link against the static image if you want. Some features which aren't used often (like pthread_yield() for instance()) aren't implemented. If you read the forms, people are skeptical of this library because it doesn't get much development attention but it works well (I think ffmpeg uses this library BTW).
