How did you run the first example? Note that the first example expects a Perl program to be loaded from the command line which implements a routine with the name showtime.

It's weird that your second example crashes when accessing ERRSV because that variable should always exist.

According to the documentation, call_argv immediately calls your function. Note that you need to deal with the return values yourself in C.
