SafeArrayPutElement function (oleauto.h)

Stores the data element at the specified location in the array.

Syntax

HRESULT SafeArrayPutElement(
  [in] SAFEARRAY *psa,
  [in] LONG      *rgIndices,
  [in] void      *pv
);

Parameters

[in] psa

An array descriptor created by SafeArrayCreate.

[in] rgIndices

A vector of indexes for each dimension of the array. The right-most (least significant) dimension is rgIndices[0]. The left-most dimension is stored at rgIndices[psa->cDims – 1].

[in] pv

The data to assign to the array. The variant types VT_DISPATCH, VT_UNKNOWN, and VT_BSTR are pointers, and do not require another level of indirection.

Return value

This function can return one of these values.

Remarks

This function automatically calls SafeArrayLock and SafeArrayUnlock before and after assigning the element. If the data element is a string, object, or variant, the function copies it correctly when the safe array is destroyed. If the existing element is a string, object, or variant, it is cleared correctly. If the data element is a VT_DISPATCH or VT_UNKNOWN, AddRef is called to increment the object's reference count.
