This function frees the destination variant and makes a copy of the source variant.
HRESULT VariantCopy( VARIANTARG FAR* pvargDest, VARIANTARG FAR* pvargSrc );
[out] Pointer to the VARIANTARG to receive the copy.
[in] Pointer to the VARIANTARG to be copied.
The following table shows the HRESULT values that can be returned by this function.
|DISP_E_ARRAYISLOCKED||The variant contains an array that is locked.|
|DISP_E_BADVARTYPE||The source and destination have an invalid variant type (usually uninitialized).|
|E_OUTOFMEMORY||Memory could not be allocated for the copy.|
|E_INVALIDARG||One of the arguments is invalid.|
Passing invalid (and under some circumstances NULL) pointers to this function causes an unexpected termination of the application.
First, free any memory that is owned by pvargDest, such as VariantClear (pvargDest must point to a valid initialized variant, and not simply to an uninitialized memory location). Then pvargDest receives an exact copy of the contents of pvargSrc.
If pvargSrc is a VT_BSTR, a copy of the string is made. If pvargSrc is a VT_ARRAY, the entire array is copied. If pvargSrc is a VT_DISPATCH or VT_UNKNOWN, AddRef is called to increment the object's reference count.
OS Versions: Windows CE 2.0 and later.
