An option to be able to check why a program which do
not print any error message fail.

On old version of strace (4.4.90) the option -z for
"only succeeding syscalls". Well the opposite options
would be a lot more helpfull :)

    The -z option didn't really work.

    I redid the patch, I have to submit it (if the -z option is
    envoked, it goes through a buffer instead of outputing to
    the screen, and the decision to output is made at the
    completion of the syscall...that means hanging syscalls
    don't print partially...

    I just needed the -z option at work and didn't have it --

    An inverse -z is very easy, any suggestions how to activate it?
