kernel/system.h

   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)
