Trying to debug a few lines of code I use Printf() because I cant use stdio printf() when I use SDL (I dont know why).
The problem is that Printf() doesnt show my data.

A little example:

Code:
```
include<stdio.h>
#include<proto/dos.h>

typedef struct datos
{
	int x;
}datos;

datos misdatos;

datos *p_data = &misdatos;

void showdata(datos *data)
{
	printf("Dato X: %dn", data->x);
}

int main()
{
	p_data->x = 100;
	showdata(p_data);
	return 0;
}
```
If I use stdio version It works well but with DOS version it shows always Dato X: 0.

There is a bug somewhere, try:

printf("Dato X: %ld\n", data->x);

Hi! It works in this simple example. Any other bug to be aware? ;)

Thanks naTmeg!

No, except you could optimize:

typedef struct datos {
int x;
}datos;

to

typedef struct {
int x;
}datos;
