FreePropVariantArray function (combaseapi.h)

The FreePropVariantArray function calls PropVariantClear on each of the PROPVARIANT structures in the rgvars array to make the value zero for each of the members of the array.

Syntax

HRESULT FreePropVariantArray(
  [in] ULONG       cVariants,
  [in] PROPVARIANT *rgvars
);

Parameters

[in] cVariants

Count of elements in the PROPVARIANT array (rgvars).

[in] rgvars

Pointer to an initialized array of PROPVARIANT structures for which any deallocatable elements are to be freed. On exit, all zeroes are written to the PROPVARIANT structure (thus tagging them as VT_EMPTY).

Return value

This function returns HRESULT.

Remarks

FreePropVariantArray calls PropVariantClear on an array of PROPVARIANT structures to clear all the valid members. All valid PROPVARIANT structures are freed. If any of the PROPVARIANT structures contain illegal VT types, valid members are freed and the function returns STG_E_INVALIDPARAMETER.

Passing NULL for rgvars is legal, and produces a return code of S_OK.
