/* Function prototypes for the system library. The prototypes in this file * are undefined to NULL if the kernel call is not enabled in config.h. * The implementation is contained in src/kernel/system/. * * The system library allows to access system services by doing a kernel call. * System calls are transformed into request messages to the SYS task that is * responsible for handling the call. By convention, sys_call() is transformed * into a message with type SYS_CALL that is handled in a function do_call(). * * Changes: * Mar 01, 2010 SYS_CLEAR and SYS_EXIT split (Cristiano Giuffrida) * Jul 30, 2005 created SYS_INT86 to support BIOS driver (Philip Homburg) * Jul 13, 2005 created SYS_PRIVCTL to manage services (Jorrit N. Herder) * Jul 09, 2005 updated SYS_KILL to signal services (Jorrit N. Herder) * Jun 21, 2005 created SYS_NICE for nice(2) kernel call (Ben J. Gras) * Jun 21, 2005 created SYS_MEMSET to speed up exec(2) (Ben J. Gras) * Jan 20, 2005 updated SYS_COPY for virtual_copy() (Jorrit N. Herder) * Oct 24, 2004 created SYS_GETKSIG to support PM (Jorrit N. Herder) * Oct 10, 2004 created handler for unused calls (Jorrit N. Herder) * Sep 09, 2004 updated SYS_EXIT to let services exit (Jorrit N. Herder) * Aug 25, 2004 rewrote SYS_SETALARM to clean up code (Jorrit N. Herder) * Jul 13, 2004 created SYS_SEGCTL to support drivers (Jorrit N. Herder) * May 24, 2004 created SYS_SDEVIO to support drivers (Jorrit N. Herder) * May 24, 2004 created SYS_GETINFO to retrieve info (Jorrit N. Herder) * Apr 18, 2004 created SYS_VDEVIO to support drivers (Jorrit N. Herder) * Feb 24, 2004 created SYS_IRQCTL to support drivers (Jorrit N. Herder) * Feb 02, 2004 created SYS_DEVIO to support drivers (Jorrit N. Herder) */ #ifndef SYSTEM_H #define SYSTEM_H #include "kernel/kernel.h" int do_exec(struct proc * caller, message *m_ptr); #if !
