Hi Ahmad,
here is an example which is trying to show what happens using a
vtkSmartPointer. Notes are in the comments.
#include <vtkSmartPointer.h>
#include <vtkDoubleArray.h>
#define PI 3.14159
void myConsumerFunction(vtkDoubleArray* doubleArray) {
// use your doubleArray or change it
// but don't use malloc or free on the array!
}
void myProducerFunction() {
const int numberOfValues = 360;
vtkSmartPointer<vtkDoubleArray> myDoubleArray =
vtkSmartPointer<vtkDoubleArray>::New();
myDoubleArray->SetNumberOfComponents(1);
myDoubleArray->SetNumberOfTuples(numberOfValues);
// fill array
for(int i = 0; i < numberOfValues; i++)
myDoubleArray->SetTuple1(i, sin(i/180.*PI));
myConsumerFunction(myDoubleArray);
}
int main(int, char*[])
{
myProducerFunction();
// immediately after myProducerFunction() has returned
// myDoubleArray is out of scope and is being deleted automatically.
// There's no need to delete myDoubleArray explicitely anymore
//...
// more function calls
// ...
return EXIT_SUCCESS;
}
with kind regards
Jochen
