When I copy the struct from the includes it says that it is already defined. I hope I get better at this soon.

So, I have two programs, one that needs to be resident and is very small. The other is going to be larger and will unload when not needed. So, how could I access variables from the resident program from the normal one? Unfortunately I can not do this differently.

Edit{
Forgot nl_set_resident();
}
So, I am trying to get a hang of the drivers, so I am making a simple one. When I plug the 360 controller in, it crashes my calculator, I thick it is in attach, don't know for sure.
main.c:
#include <os.h>
#include <usbdi.h>
#include <usb.h>
#include <nspireio2.h>
int main(void) {
assert_ndless_rev(750);
register360();
nl_no_scr_redraw();
nio_grid_puts(0, 0, 12, 1, "360 drivers installed!", is_cx ? NIO_COLOR_BLACK : NIO_COLOR_WHITE, is_cx ? NIO_COLOR_WHITE : NIO_COLOR_BLACK);
return 0;
}

So, I am a programmer/modder/gamer, for the most part if it uses electricity I want to take it apart, reprogram it, mod it, etc. I hope to be a good thing when it comes to nspire cx, as I got mine in August, I already have many ideas for it.

I would like to create a virtual directory in the root of the file explored on the cx, how would I go about doing this in c?
