| * @brief Header for platform missing functions. |
| * @author Karlson2k (Evgeny Grin) |
| * |
| * Provides compatibility for platforms with some missing |
| * functionality. |
| * Any functions can be implemented as macro on some platforms |
| * unless explicitly marked otherwise. |
| * Any function argument can be skipped in macro, so avoid |
| * variable modification in function parameters. |
