multi_vfs_ntpd example

This example shows how to use an external NTP server in KasperskyOS. The Ntpd program is included in KasperskyOS Community Edition and is an implementation of an NTP client, which gets time parameters from external NTP servers in the background and passes them to the KasperskyOS kernel.

The example also demonstrates the use of various virtual file systems (VFS) in a single solution:

• The VfsNet program is used for working with the network.
• The VfsSdCardFs program is used to work with the file system.

The Client program uses standard libc library functions for getting time data. These functions are converted into queries to the VFS program via IPC.

The CMake system, which is included with KasperskyOS Community Edition, is used to build and run the example.

Supplied resources

• The directory ./resources/edl contains the Client.edl file, which contains a static description of the Client program.
• The directory ./resources/hdd/etc contains the configuration files for the VfsNet, Dhcpcd and Ntpd programs: hosts, dhcpcd.conf and ntp.conf, respectively.
