Hello,
can it be that the sigaction() funtion for signal handling is not supported
on qnx6.3.2. This function returns an error. strerror(errno) return “Not
supported”. However the same code works on another system with qnx6.3.0,
SP2.

There is no intention or expectation that sigaction() will stop working with
6.3.2, and I have used it.
Can you post your call (with all the setup structures) that has stopped
working?
Is it possible you’ve not initialized one of the structures passed
in, and that you were lucky to get “safe” values in an earlier compile, but
not with a more recent build?

I’m not at my system to test this right now, but I would imagine a lot
of things would break if this were the case. 6.3.2 has been out long
enough that this is unlikely. Maybe it is something more
circumstantial, a bad signal number or perhaps trying to use a signal
which requires super user privileges when they are not available?
Maybe post your sigaction code?
hello David,
thanks for the support. the file contains the piece of code with the
sigaction call.

Hello,
i found the error. it didn’t set thte sigaction structure element “sa_flags”
to 0. the default value was 0xffffffff.
Now that i set it to 0, every thing is functioning very well.
Thanks for your help.
