This function copies the contents of one PROPVARIANTstructure to another.
Syntax
WINOLEAPI PropVariantCopy( PROPVARIANT* pvarDest, const PROPVARIANT* pvarSrc ); |
Parameters
- pvarDest
-
[in, out] Pointer to an uninitialized PROPVARIANTstructure that receives the copy.
- pvarSrc
-
[in] Pointer to the PROPVARIANTstructure to be copied.
Return Values
The following table shows the return values for this function.
Value | Description |
---|---|
S_OK |
The copy was successfully completed. |
STG_E_INVALID_PARAMETER |
The variant has an unknown type. |
Remarks
Copies a PROPVARIANTstructure by value so the original pvarSrcand new pvarDestparameters may be freed independently with calls to PropVariantClear. PropVariantCopydoes not free the destination as the VariantCopyfunction does. For nonsimple PROPVARIANTtypes such as VT_STREAM, VT_STORAGE, and so forth, which require a subobject, the copy is made by reference. The pointer is copied and IUnknown::AddRefis called on it. It is illegal to pass NULL for either pvarDestor pvarSrc.
