artswrapper(7) Arts artswrapper(7) NAME
artswrapper - used to set real-time priority to artsd, the KDE sound system SYNOPSIS
artswrapper [OPTION] DESCRIPTION
artswrapper gives artsd the capability of running with real-time scheduling priority. This helps prevent audio skips and jumps. Except for the check option, artswrapper passes all other arguments directly to artsd. Artswrapper calls the arguments after setting the real-time priority and dropping privileges (if running as setuid root). The real-time status is passed to artsd via the environment variable STARTED_THROUGH_ARTSWRAPPER, and can be one of the following values: unset (not running as real-time), 1 (running as real-time), 2 (no privileges to set real-time scheduling), or 3 (no support for real-time scheduling). OPTIONS
check backward compatibility with old artswrapper. This only prints "okay" and exits. SECURITY
artswrapper must be used as setuid root to have privileges to set real-time scheduling. BUGS
Sometimes artsd locks the system on exit in 2.4 kernels. If this happens, use aKode library, which improves the CPU usage, helps maintain uninterrupted sound, and remove the setuid bit from artswrapper (thanks to Debian documentation and Christopher Martin). SEE ALSO
artsd, artsdsp AUTHOR
