i have no idea if there is a manual for that.
i usually use foreach loop trough inputs args, to see what is there.
u have also ioFTPD environmnet variables (PATH, USER, SPEED, ...) available in your program. u can find them in /etc/ folder i think.
just use a method as if u were looking for some WINDOWS ENV variable.
Code:
windows:
Environment.GetEnvironmentVariable("windir");
...
ioFTPD:
Environment.GetEnvironmentVariable("USER"); //username of the user who uploaded the file
Environment.GetEnvironmentVariable("SPEED"); //average speed the file was uplaoded with
...
here is also nice example to start with:
