inb() and outb()

[Belinda]

Hi, all

I wrote a simple program with inb() and outb().
However, it reports the segmentation error when
running it. 

The code follows as: 
---------------------------------
#include <asm/io.h>

#define LPT 0x378

void write_LPT(unsigned char byte) 
{
    outb(byte, LPT);
}

int main()
{
   write_LPT(LPT);
   printf("Value:%c", inb(LPT));

}
------------------------------------------------------

Thanks,

Belinda
