Hello, I have the following example code:


#include <EXTERN.h>
#include <perl.h>

static PerlInterpreter *my_perl;

void hello ()
{
  printf("Hello, world!\n");
}

int main (int argc, char **argv, char **env)
{
  PERL_SYS_INIT3(&argc, &argv, &env);
  my_perl = perl_alloc();
  perl_construct(my_perl);
  PL_exit_flags |= PERL_EXIT_DESTRUCT_END;
  perl_parse(my_perl, NULL, argc, argv, (char **)NULL);
  perl_run(my_perl);
  perl_destruct(my_perl);
  perl_free(my_perl);
  PERL_SYS_TERM();
  
  return 0;
}

How do I make the "hello" function available to the "my_perl" interpreter?

This case seems to be not covered in documentation.

The closest thing is, probably, to create a separate xs module with a dynamic library and to evaluate "use Separate::Module" statement, exporting necessary subroutines into perl.

Also there is a "newXSproto" function, but I'm not sure how to use it and if it's at all relevant here
