(argument 1) Invalid buffer pointer

[hooshdar3]

Hi.
What's wrong with the following call:

   MPI_Scatter( A[0], chunk * m, MPI_INT, &(buffer[0][0]),
		                       chunk * m, MPI_INT,0, MPI_COMM_WORLD );

?The definition of the function is:

int MPI_Scatter(void *sendbuf, int sendcnt, MPI_Datatype sendtype, 
               void *recvbuf, int recvcnt, MPI_Datatype recvtype, int root, 
               MPI_Comm comm)

and array A is defined thus:

	 int 	**A, **B, **C;   //Arrays to be created
.
.
.
	 A = new int *[n];
	 
	 for(row=0;row<n;++row)
       A[row] = new int[m];

Thanks in advance
