I have to use these functions:

pcireg_t    pci_conf_read __P((pci_chipset_tag_t, pcitag_t, int));
void        pci_conf_write __P((pci_chipset_tag_t, pcitag_t, int,
		pcireg_t));
void        *pci_map_int __P((pcitag_t, int, int (*)(void *), void *));
int         pci_map_io __P((pcitag_t, int, int *));
int         pci_map_mem __P((pcitag_t, int, vm_offset_t *,
		vm_offset_t *));

What are the equivalent ones to use to write a machine indipendent code?
