9 * - OS specific initialization/finalization
10 * - process termination
11 * - error handling
12 * - conversion of error codes to error messages
13 * - low-level memory allocation
14 * - program startup
15 * - time management
16 * - process times (user time, system time and real time).
17 * - heartbeat interrupt handling
18 * - user interrupt handling
19 * - access to OS environment variables
20 * - shell command
21 * - dynamic loading
22 * - dynamic C compilation
23 * - floating point environment setup
24 * - processor count
25 * - processor cache size
26 * - virtual memory statistics
27 * - filesystem path expansion
28 * - formatting of source code position
29 * - operations on I/O devices
