SafeArrayCreateVectorEx function (oleauto.h)
Creates and returns a one-dimensional safe array of the specified VARTYPE and bounds.
SAFEARRAY * SafeArrayCreateVectorEx(
[in] VARTYPE vt,
[in] LONG lLbound,
[in] ULONG cElements,
[in] PVOID pvExtra
);
[in] vt
The base type of the array (the VARTYPE of each element of the array). The FADF_RECORD flag can be set for VT_RECORD. The FADF_HAVEIID can be set for VT_DISPATCH or VT_UNKNOWN and FADF_HAVEVARTYPE can be set for all other types.
[in] lLbound
The lower bound for the array. This parameter can be negative.
[in] cElements
The number of elements in the array.
[in] pvExtra
The type information of the user-defined type, if you are creating a safe array of user-defined types. If the vt parameter is VT_RECORD, then pvExtra will be a pointer to an IRecordInfo describing the record. If the vt parameter is VT_DISPATCH or VT_UNKNOWN, then pvExtra will contain a pointer to a GUID representing the type of interface being passed to the array.
A safe array descriptor, or null if the array could not be created.
