Subject: NcVar put method
I am trying to use this method signature -NcBool put(const ....* vals, const
long* counts)-; but I have a problem , can some one please tell me what is my
mistake .
Why - data->put(&dataOut[0],*dim);- is not working. Please see the code.
#include <iostream>
#include <netcdfcpp.h>
using namespace std;
// We are writing 2D data, a 6 x 12 grid.
static const int NDIMS = 2;
static const int NX = 6;
static const int NY = 12;
// Return this in event of a problem.
static const int NC_ERR = 2;
int main(void)
{
// Different ways to write arrays
int dataOut[NX * NY];
int dataOut2[NX] [NY];
// Create some pretend data. Note that dataOut and dataOut2 are
identical...!!!
for(int i = 0; i < NX; i++)
for(int j = 0; j < NY; j++){
dataOut[i * NY +j] = (i+1) * (j+1);
dataOut2[i][j] = (i+1) * (j+1);
}
// Create the file.
NcFile dataFile("simple_xy.nc", NcFile::Replace);
if (!dataFile.is_valid())
{
cout << "Couldn't open file!\n";
return NC_ERR;
}
NcDim* xDim = dataFile.add_dim("x", NX);
NcDim* yDim = dataFile.add_dim("y", NY);
const NcDim* all[2] ;
all[0] = xDim;
all[1] = yDim;
int *dim;
dim = new int[2];
dim[0] = 6;
dim[1] = 12;
NcVar *data = dataFile.add_var("data", ncInt, 2, all);
NcVar *data2 = dataFile.add_var("data2", ncInt, 2, all);
// This works fine and data and data2 are identical
// data->put(&dataOut[0],NX, NY);
data2->put(&dataOut2[0][0], NX, NY);
// try to use another signature
data->put(&dataOut[0],*dim); //nothing is written
cout << "*** SUCCESS writing example file simple_xy.nc!" << endl;
return 0;
}
