  [in, out] SAFEARRAY      *psa,
  [in]      SAFEARRAYBOUND *psaboundNew
);

Parameters

[in, out] psa

A safe array descriptor.

[in] psaboundNew

This function can return one of these values.

Return code Description
S_OK
 Success.
E_INVALIDARG
 The argument psa is not valid.
DISP_E_ARRAYISLOCKED
 The array is locked.

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.
