This function changes the right-most or least significant bound of a safearray.

Syntax

HRESULT SafeArrayRedim(
  SAFEARRAY FAR* psa, 
  SAFEARRAYBOUND FAR* psaboundNew 
);

Parameters

  • psa
    [in] Pointer to an array descriptor.

  • psaboundNew
    [out] Pointer to a new safearray bound structure that contains the new array boundary.

    Only the least significant dimension of an array can be changed.

Return Value

Value

Description

S_OK

Success.

DISP_E_ARRAYISLOCKED

The array is locked.

E_INVALIDARG

The item pointed to by psa is not a safearray 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 the old and new array.

Passing invalid (and under some circumstances NULL) pointers to this function causes an unexpected termination of the application.
