MFX callback function require 3 parameters to make developers' life.
pState - is a pointer to the performing object or something like this.
pParam - is an addition parameter to destingush one task from the another inside
the entry point. It is possible to start different threads with the same
object (pState), but different task (pParam). Usually, it is a handle or some
internal pointer.
