multi_vfs_dns_client example

This example shows how to use an external DNS server in KasperskyOS.

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 contacting an external DNS service. These functions are converted into queries to the VfsNet 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 and Dhcpcd programs: hosts and dhcpcd.conf, respectively.
