/* Function prototypes for the system library. The implementation is contained
 * in src/kernel/system/. The system library allows to access system services
 * by doing a system call. System calls are  transformed into request messages
 * to the SYS task that is responsible for handling the call. By convention, a
 * sys_call() is transformed into a message with type SYS_CALL that is handled
 * in a function named do_call().
