The system call set

A kernel might be defined as the set of functions that it implements. The full system call set is declared in the file include/sartoris/syscall.h:

/* sartoris system calls */

#ifndef SYSCALL
#define SYSCALL

#include $<$sartoris/kernel.h$>$

/* multitasking */
int create_task(int address, struct task *tsk, int *src, int init_size);
int destroy_task(int task_num);

/* threading */

int destroy_thread(int id);
int run_thread(int id);
int set_thread_run_perm(int thread, int perm);
int set_thread_run_mode(int priv, int mode);

/* interrupt handling */
int create_int_handler(int number, int thread, int nesting, int priority);
int destroy_int_handler(int number, int thread);

/* message-passing */
