SV: FTPAPI FTP_exitproc

["Helge Bichel" <hbi@xxxxxxx>]

Hi Scott,

I have followed your suggestion and tested the splitting of FTP_Conn into
FTP_Open / Ftp_Login with the Ftp_ExitProc in between.
That?s works perfect.

Thanks for your help.

Helge

Helge,

Yes, this is the expected behavior.  when you register an exitProc with
FTP_DEFAULT_SOCKET it will apply to all new connections that are created 
thereafter.    Unless this is what you want, you should not use the 
FTP_DEFAULT_SOCKET.

FTP_Conn() has actually been split into two separate procedures for exactly
this reason.  The new procedures are FTP_Open() which establishes the socket
number, and FTP_Login() which does the login portion of the FTP protocol.
In current versions of FTPAPI, FTP_Conn() actually just calls these two
procedures in succession.

So you should change your code to:

FtpSess  = FTP_Open(FtpRmtSys: FTPPort: FTPCnnTio);

FTP_exitProc( FtpSess: FTP_EXTLOG: %paddr(FTPExitProc): %addr(LastMsg));

if FTP_Login( FtpSess: FtpUsr: FtpPwd ) < 0;
     // error occurred.
endif;

Now the exit procedure will only fire for this particular session, and will
not apply to any others.

You'll want to call FTP_Quit() when this FTP session is done (unless
FTP_open failed for some reason.)
