Hi Vladimir,

static functions only known inside the same object file.
So the linker can not resolve calling it from another object.

In general local subfunctions declared as static for better readable sources. Then you are able to modify such functions and be sure, that other objects never affected.
Also it is possible to use the same name for different subfunctions in different objects (but not wise).

On using debugger or emulator you should avoid static functions, since they are invisible.
