Get an FTP Listing Entry's Permissions

Demonstrates the Chilkat Ftp2.GetPermissions method, which returns the permissions or status string of a cached directory-listing entry. The only argument is a zero-based index. The value is empty when the server provides no such metadata.

Background: FTP has no single standard permissions format, so what this returns depends on the server — commonly a Unix-style mode string like drwxr-xr-x, but potentially something else. Because the format varies, pair it with GetPermType to learn how to interpret the string before parsing it, rather than assuming a fixed layout.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.
