It is not available for use in Windows Server 2003 with Service Pack 1 (SP1) and later, Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The Smart Card Modules provide similar functionality.]

The CreateSafeArray method creates an Automation SAFEARRAY of unsigned characters (bytes).

  [in]  UINT        nAllocSize,
  [out] LPSAFEARRAY *ppArray
);

Parameters

nAllocSize [in]

Size in bytes of the memory to be allocated for the array.

ppArray [out]

Memory allocated successfully.
E_INVALIDARG
There is something wrong with one or more of the parameters passed into the function.
E_OUTOFMEMORY
