Set a Remote File's POSIX Permissions

See more SFTP Examples

Demonstrates the Chilkat SFtp.SetPermissions method, which sets the POSIX permission bits of a remote item. The arguments are the remote path (or handle), whether the first argument is a handle, and the permission bits. Pass the permission bits only, not the file-type bits.
