Re: LONGS returned from DLL call

Since it seems like I typically get zero or little, it doesn't look like a
pointer.
The docs for the C template are from the freeware FTP4W ftp library. It
shows a long returned, not a pointer to a long.

I haven't ruled out that there is a bug in this library somewhere. For
example,
messages don't seem to be generated by FtpSendFile, while they do get
generated from the FtpDir function, for example, which signals the message
loop after each file name is read. However, putting FtpBytesTransferred in
a busy loop doesn't seem to give valid values either.

Let's not get too involved in this, as I am beginning to suspect a buggy
freeware library here... the return of a long notwithstanding.

Should sForth push 2 values on the stack in such cases?

\ *******************************************************
\ FTP4W docs simply show: long FtpBytesTransferred(VOID)

LIBRARY FTP4W32.DLL

\ 1 IMPORT: RegisterWindowMessage
0 IMPORT: FtpBytesTransferred

\ OUTBUFF = z$destination file
\ INBUFF = z$localsourcefile
\ MyFTPMessage, user "WM_MESSAGE"
\ FtpSendFile, when the ftp4w is initialized
\ for asynchronous mode, will send windows a
\ message after sending a bunch of packets, this
\ allows tracking the progress of ftp data
\ transfers.
OUTBUFF INBUFF TYPE_I 1 ( <- sendmsg flg ) hWND MyFTPMessage FtpSendFile if
...

\ elsewhere, such as in windows message loop:
      FtpBytesTransferred ( .s ) \ --> depth = 1
\ ...................
\ clearly, since the bytes transferred would need to show
\ valid values for large file transferes, should be a long
\ value.
