Description

Extracts an array of ULONGINT values from DVARIANT.

Remarks

This helper function is used when the calling application expects a DVARIANT to hold an array of ULONGINT values.

If DVARIANT is of type VT_ARRAY OR VT_UI8, this function extracts an array of ULONGINT values into a newly allocated array. The calling application is responsible for using CoTaskMemFree to release the array pointed to by pprgn when it is no longer needed.
