Extracts an array of LONGINT values from DVARIANT.

COMmethodDVARIANT.INCdocumented

Syntax

FUNCTION ToLongIntArray (BYVAL prgn AS LONGINT PTR, BYVAL crgn AS ULONG) AS ULONG

Parameters

NameDescription
prgnPointer to a buffer that contains crgn LONGINT variables. When this function returns, the buffer has been initialized with Int64 elements extracted from DVARIANT.
crgnThe number of elements in the buffer pointed to by prgn.

Return value

This helper function is used when the calling application expects a VARIANT to hold an array that consists of a fixed number of Int64 values.

If the source VARIANT is of type VT_ARRAY OR VT_UI4, this function extracts up to crgn Int64 values and places them into the buffer pointed to by prgn. If the VARIANT contains more elements than will fit into the prgn buffer, this function returns 0.
