I created the following function and my program crashed. If it is not possible for functions to call themselves, what would a reasonable workaround be?

void move_tab (MENU_TAB* m, int a)
{
int j = 0;
int k = 0;
while (k <= m->pan_num)
{
m->panels[k]->pos_y += a;
k += 1;
}
k = 0;
while (k <= m->tex_num)
{
m->texts[k]->pos_y += a;
k += 1;
}
k = 0;
while (k <= m->tab_num)
{
move_tab (m->sub_tabs[0], a);
k += 1;
}
}

Thanks in advance!

Functions calling themselves are called recursive functions. Might be of help for you when researching.

Anyhow, I think it's relating to how you pass your pointer to the function, maybe resulting in an infinite loop at the first function. Try without the loops but just a small counter (and global counter variable), does it still crash? Try to think of more testcases to get the piece of code causing the crash. Because recursive functions work fine, I did it.

Thanks for the fast response!

I went through some tests and it turns out I had an empty pointer in one of my structs.
Sorry for the trouble.

Afaik all recursive functions can be written as iterative functions (loop) and it's faster.
