SafeArrayDestroy function (oleauto.h)
Destroys an existing array descriptor and all of the data in the array. If objects are stored in the array, Release is called on each object in the array.
Syntax
HRESULT SafeArrayDestroy(
[in] SAFEARRAY *psa
);
Parameters
[in] psa
An array descriptor created by SafeArrayCreate.
Return value
This function can return one of these values.
Return code | Description |
---|---|
|
Success. |
|
The argument psa is not valid. |

The array is locked. |
Remarks
Safe arrays of variant will have the VariantClear function called on each member and safe arrays of BSTR will have the SysFreeString function called on each element. IRecordInfo::RecordClear will be called to release object references and other values of a record without deallocating the record.
Examples
STDMETHODIMP_(ULONG) CEnumPoint::Release()
{
if(--m_refs == 0){
if(m_psa != NULL)
SafeArrayDestroy(m_psa);
delete this;
return 0;
}
return m_refs;
}
