DESCRIPTION

rtftclx is a package that makes it possible to handle Real-Time Fifos from a Tcl script.
In what follows RTF stands for Real-Time FIFOS.

Real-Time Fifos are Unix devices used by RTLinux and RTAI.
Tcl cannot directly open/close/access to RTFs.
Instead of writing Tcl's device handlers for RTFs, I have dveloped this package.
Most operations are programmed in C, because C can access to RTFs as ordinary files.
 

COMMANDS

rtf_debug Boolean-exp

If Boolean-exp evaluates to 0 then the debugging for RTF is disabled; else it is enabled.

Default is debugging off.
