Hello,
I have a problem with NetCDF C++ Library.
I have to write a netcdf file with 4-dimension data (providing from a
grib file).
I use the code below:
float values[NT][NZ][NJ][NI];
for (it = 0; it < NT; it++) {
for (iz = 0; iz < NZ; iz++) {
for (j = 0; j < NJ; j++) {
for (i = 0; i < NI; i++) {
values[it][iz][j][i] = ....;
}
}
}
}
var->set_cur(0,0,0,0); //using NcVar var
var->put(&values[0][0][0][0], NT, NZ, NJ, NI);
This works fine, the netcdf file is correct, the data are saved
properly. But, with this 'static' 4-dim array declaration, i am using
the stack memory which is limited. With big data, i could have a
segmentation fault...
So I'd like to dynamically declare the values array.
I am using this code below:
float * values = (float *) malloc(NT*NZ*NJ*NI*sizeof(float));
for (it...)
for (iz ...)
for (j ...)
for (i...)
values[it*NZ+iz*NJ+j*NI+i] = ....;
var->set_cur(0,0,0,0);
var->put(values, NT, NZ, NJ, NI);
In this case, a netcdf file is generated, but the data are not saved
properly.
Do you know why this happens and how can I solve the problem?
Thanks,
Carole
