Q: How do I trace system calls?

Hi there,

I am searching for a tool, which enables my to trace system calls?
Something like truss (SOLARIS) or strace (Linux).

Is there such a thing out there?


TIA,

lojo

Assuming you’re talking about QNX4 – look at tracectrl. Also, traceinfo
to see the results of the Trace() calls.

Thanks David,

but unfortunately (in respect of this thread) I have QNX/Neutrino/PPC
as target platform. Are there ports for traceXXX()/Trace() available?
Or something similar?

Thanks in advance,

Artur

Take a look in the documentation for slogger and sloginfo, and the
slog*() calls.

I don’t have docs here, but are those high-speed tracing calls ? Can you
put slog() calls in interrupt handlers, etc. (as you can with Trace calls) ?

According to the docs, they appear to be message based.

(And, they appear to be fairly new… they may be in RTP, but not in
the current released stuff for PPC.)
