Part 1. Simple application (POSIX)
Part 1. Simple application (POSIX)
KasperskyOS Community Edition includes a set of libraries (libc, libm and libpthread) ensuring that the developed applications are partially compatible with the POSIX family of standards.
This part of the Guide illustrates the following:
- Printing a string to the screen by using
fprintf() - Using VFS component for working with a network and file systems
- Creating the
Einitinitializing entity - POSIX support limitations
To simplify the descriptions, the example in this part of the Guide is built without the ksm.module. For this reason, when example is started, a notification WARNING! Booting an insecure kernel! is displayed. The third part of the Guide examines a solution security policy, use of security policies, and building ksm.module.
