Syntax
HRESULT SafeArrayRedim(SAFEARRAY FAR* psa, SAFEARRAYBOUND FAR* psaboundNew);
Parameters
psa
Pointer to an array descriptor.
psaboundNew
Pointer to a new safe array bound structure that contains the new array boundary. Only the least significant dimension of an array can be changed.
Return Values
One of the values obtained from the returned HRESULT and described in the following table is returned.
Value | Description |
S_OK | Success. |
DISP_E_ARRAYISLOCKED | The array is currently locked. |
E_INVALIDARG | The item pointed to by psa is not a safe array descriptor. |
Remarks
If you reduce the bound of an array, SafeArrayRedim deallocates the array elements outside the new array boundary. If the bound of an array is increased, SafeArrayRedim allocates and initializes the new array elements. The data is preserved for elements that exist in both the old and new array. Passing into this function any invalid and, under some circumstances, NULL pointers will result in unexpected termination of the application.
