According to the ppi man page it's..
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <dev/ppbus/ppi.h>
#include <dev/ppbus/ppbconf.h>
int
main(int argc, char **argv) {
int fd;
if ((fd = open("/dev/ppi0", O_RDWR)) == -1) {
printf("Can't open /dev/ppi0\n");
exit(1);
}
exit(0);
}
Those includes are present on my 7.2 box (upgraded with the last week)
and my (oldish) -current box.
