How to use outb( ) and inb( ) with gcc and FreeBSD?
The following program compiles and run in linux but it does not compile
using FreeBSD. It compiles in linux using: gcc -O2 prog1.c -o prog. It
dos NOT
compile using FreeBSD because of the include file "asm/io.h".
#include <stdio.h>
#include <unistd.h>
#include <asm/io.h>
#define BASEPORT 0x378 /* lpt port. */
int main()
{
/* Getting accesss to io port. */
if (ioperm(BASEPORT, 3, 1) {perror("ioperm"); exit(1);}
again:
outb(0, BASEPORT);
sleep(1);
outb(0xFF, BASEPORT);
sleep(1);
printf("Testing...\n");\
goto again;
}
What changes would be necessary for a simillar program to work with
FreeBSD?

Thanks.
