Re: When call_argv() actualy executes function

[Corion]

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.

Thank you for documentation link! Yes, I'm launching it from cmd like very_simple_example_that_does_not_works.exe showtime.pl. If I don't launch it like that - it shows error undefined subroutine
