How about you declare argc and argv as globals in your main app, like so ...

int argc;
char** argv;

int main(void)
{
}

and then in your lib you do :

extern int argc;
extern char** argv;

Then, you *should* be able to call argv/argc like you normally would do ?

Untested, but I don't see why this wouldn't work.
