IFTPPortPool Interface

This interface is implemented by the FTPPortPool class.

IFTPPortPool

IDL

interface IFTPPortPool : IDispatch;

File

sfFTPLib.idl

Remarks

The FTPPortPool class is a singleton and can be used to limit the ports IFTPConnection is using to open an active data connection (PORT). To use the port pool, set the port range and limit the ports by setting the LimitLocalPortRange property of the IFTPConnection interface to true.
