Return vba array from user defined function

I'm having difficulties with the basics of passing an array from a function in VBA.
To be used in vba macros in MS Office (Excel & Visio), but without reference to excel ranges.

I start by making a simple dynamic array:

Sub makeArray()
Dim arrItems() As Long
Dim i As Integer
Dim m As Long
m = 2
For i = 0 To 9
ReDim Preserve arrItems(i + 1)
arrItems(i) = i * 10 * m
Next i
For i = 0 To UBound(arrItems) - 1
Debug.Print "arrItems(" & i & ") = "; arrItems(i)
Next i
End Sub

How do I convert the above to a function to be called from this Sub():
Sub doMakeArray()
myArray() as long
Dim m as long
m = 2
myArray =doMakeArray(m)
end sub

I would start off:
Function doMakeArray(m as long)

I would seek to conclude:
doMakeArray = arrItems

I wish to return arrays of either strings or long - data types

Thanks
