1/* Function prototypes for the system library. The prototypes in this file
2 * are undefined to do_unused if the kernel call is not enabled in config.h.
3 * The implementation is contained in src/kernel/system/.
4 *
5 * The system library allows to access system services by doing a kernel call.
6 * System calls are transformed into request messages to the SYS task that is
7 * responsible for handling the call. By convention, sys_call() is transformed
8 * into a message with type SYS_CALL that is handled in a function do_call().
9 *
10 * Changes:
11 * Jul 30, 2005 created SYS_INT86 to support BIOS driver (Philip Homburg)
12 * Jul 13, 2005 created SYS_PRIVCTL to manage services (Jorrit N. Herder)
13 * Jul 09, 2005 updated SYS_KILL to signal services (Jorrit N. Herder)
14 * Jun 21, 2005 created SYS_NICE for nice(2) kernel call (Ben J. Gras)
15 * Jun 21, 2005 created SYS_MEMSET to speed up exec(2) (Ben J. Gras)
16 * Apr 12, 2005 updated SYS_VCOPY for virtual_copy() (Jorrit N. Herder)
17 * Jan 20, 2005 updated SYS_COPY for virtual_copy() (Jorrit N. Herder)
18 * Oct 24, 2004 created SYS_GETKSIG to support PM (Jorrit N. Herder)
19 * Oct 10, 2004 created handler for unused calls (Jorrit N. Herder)
20 * Sep 09, 2004 updated SYS_EXIT to let services exit (Jorrit N. Herder)
21 * Aug 25, 2004 rewrote SYS_SETALARM to clean up code (Jorrit N. Herder)
22 * Jul 13, 2004 created SYS_SEGCTL to support drivers (Jorrit N. Herder)
23 * May 24, 2004 created SYS_SDEVIO to support drivers (Jorrit N. Herder)
24 * May 24, 2004 created SYS_GETINFO to retrieve info (Jorrit N. Herder)
25 * Apr 18, 2004 created SYS_VDEVIO to support drivers (Jorrit N. Herder)
26 * Feb 24, 2004 created SYS_IRQCTL to support drivers (Jorrit N. Herder)
27 * Feb 02, 2004 created SYS_DEVIO to support drivers (Jorrit N. Herder)
