Accessing exported variables in DLL with dlsym().


I am trying to port a program that opens dynamic library with dlopen()
and looks up symbol with dlsym(). This works for function reference but
not for variable. The porgram is:

main.c:

#include <dlfcn.h>
#include <stdio.h>

main() {
    int (*foo)(void);
    void *libfoo;

    libfoo = dlopen ("libfoo.dll", 0);
    foo = dlsym (libfoo, "foo");
    foo();
}

foo.c:

#include <stdio.h>
#include <dlfcn.h>

__declspec (dllexport) extern foo (void);

foo() {
    char *bar;
    void *libbar;

    libbar = dlopen ("libbar.dll", 0);
    bar = dlsym (libbar, "bar");
    puts (bar);
}
