CArray::GetData
Use this member function to gain direct access to the elements in an array.
const TYPE* GetData( ) const;
TYPE* GetData( );
Parameters
- TYPE
Template parameter specifying the type of the array elements.
Return Value
A pointer to an array element.
Remarks
If no elements are available, GetData returns a null value.
While direct access to the elements of an array can help you work more quickly, use caution when calling GetData; any errors you make directly affect the elements of your array.
Example
CArray<CPoint,CPoint> myArray;
// Allocate memory for at least 32 elements.
myArray.SetSize(32, 128);
// Add elements to the array.
CPoint* pPt = (CPoint*) myArray.GetData();
for (int i = 0; i < 32; i++, pPt++)
*pPt = CPoint(i, 2*i);
// Only keep first 5 elements and free extra (unused) bytes.
myArray.SetSize(5, 128);
myArray.FreeExtra();
