Using dynamic libraries

Dynamic libraries (*.so files) can be used in a KasperskyOS-based solution. Compared to static libraries (*.a files), dynamic libraries provide the following advantages:

• Efficient use of RAM.

  Multiple processes can use the same instance of a dynamic library. Also, a program and dynamic libraries in one process can use the same instance of a dynamic library.

  Dynamic libraries can be loaded into memory and unloaded from memory on the initiative of the programs that use them.

• Convenient software updates.

  A dynamic library update is applied to all programs and dynamic libraries dependent on this dynamic library without having to rebuild them.

• Capability to implement a mechanism for plug-ins.

  Plug-ins for solution components consist of dynamic libraries.

• Shared use of code and data.

  One instance of a dynamic library can be concurrently used by multiple processes, and by a program and dynamic libraries in one process. This enables centralized management of multi-access to resources or storage of shared data, for example.

Dynamic libraries are provided in the KasperskyOS SDK, and can also be created by a KasperskyOS-based solution developer. Normal operation of third-party dynamic libraries cannot be guaranteed.

Due to current technical limitations, libc.so and libpthread.so cannot be used in a KasperskyOS-based solution.
