\subsection{cron}
|
|
This module allows to install commands into SICS which will be repeated
|
|
periodically. The syntax is: sicscron intervall command. intervall is
|
|
the time intervall and command is the command to execute. A problem
|
|
is I/O becasue the original connection which installed the cron job
|
|
may be lost. Therefore cron commands are executed within the context
|
|
of special connection which does not do socket output. All I/O will be
|
|
logged into the command log though for control. As
|
|
this is a single system facility all data structure will be defined
|
|
in the implementation file. The public interface to this is just the
|
|
installation routine. This stuff is implemented in the files
|
|
sicscron.h and sicscron.c.
|
|
|
|
The installation routine installs another task into the SICS system
|
|
which will invoke the command to be executed at the predefined
|
|
intervalls.
