24 | * @author Karlson2k (Evgeny Grin) | ||
25 | * | ||
26 | * Provides compatibility for platforms with some missing | ||
27 | * functionality. | ||
28 | * Any functions can be implemented as macro on some platforms | ||
29 | * unless explicitly marked otherwise. | ||
30 | * Any function argument can be skipped in macro, so avoid | ||
31 | * variable modification in function parameters. | ||
