I have a question about using ByRef in Declares and Function calls.
Say I need to call an OS function using a Declare, and that function needs a pointer to a 4 byte integer in order to return some value. I would call this function like this: Dim i As Integer Declare Sub SomeFunc Lib "somelib" (ByRef Data As Integer) SomeFunc(i) The returned value is now in 'i'. But what happens when this code is in a subroutine that I need to call, and pass in the integer pointer? Now that code looks ike this: Sub MyFunc (ByRef i As Integer) Declare Sub SomeFunc Lib "somelib" (ByRef Data As Integer) SomeFunc(i) End Sub and I call this using Dim x As Integer MyFunc(x) Now I'm using ByRef twice. So when I call SomeFunc am I going to pass a pointer to a pointer to 'x'? _______________________________________________ Unsubscribe or switch delivery mode: <http://www.realsoftware.com/support/listmanager/> Search the archives of this list here: <http://support.realsoftware.com/listarchives/lists.html>
