Why doesnt this work...

[b1tsh1ft3r]

This seems fairly straight forward and SHOULD work. Is there something i am missing here? The idea was to have a global integer variable
that could change what was drawn in the draw_screen function.

vars.h

Code: [Select]

#ifndef __VARS_H__
#define __VARS_H__

typedef struct
{
   int test;  
} _vars;

extern _vars vars;

#endif

main.c

Code: [Select]

#include <jo/jo.h>
#include "vars.h"

void draw_screen(void)
{	
	jo_clear_screen();

	if(vars.test == 1)
	{
		jo_printf_with_color(15, 5, JO_COLOR_INDEX_White, "test 1");
	}

	if(vars.test == 2)
	{
		jo_printf_with_color(15, 5, JO_COLOR_INDEX_White, "test 2");
	}
}

void initialize(void)
{
	jo_core_init(JO_COLOR_Black);
	jo_core_add_callback(draw_screen);
	jo_core_run();
}

void jo_main(void)
{
	initialize();
	vars.test = 2;
}

Nvermind, figure out jo_core_run() is a blocking function
