SIGSYS in <signal.h>

[Andrew Josey <yyyyyy@xxxxxxxxxxxxxxxxx>]

hi All,

A topic for discussion...

The SIGSYS signal is defined in <signal.h> as an XSI extension.
>From what I can see the only use of this definition, is the definition
itself in <signal.h>

Is this a signal that portable applications can make use of?
Linux does not define the signal - apparently since it handles these
events in another way.

Views?

Andrew
