     pci_config_put8() function replaces  pci_config_putb().  The
     pci_config_put32()  function replaces pci_config_putl(). The
     pci_config_put64() function replaces pci_config_putll(). The
     pci_config_put16() function replaces pci_config_putw().

PARAMETERS
     handle    The   data    access    handle    returned    from
               pci_config_setup(9F).


     offset    Byte offset from the beginning of the  PCI  Confi-
               guration space.


     value     Output data.


DESCRIPTION
     These routines read or write a single datum of various sizes
     from  or  to  the  PCI  Local  Bus  Configuration space. The
     pci_config_get8(),  pci_config_get16(),  pci_config_get32(),
     and  pci_config_get64()  functions  read 8 bits, 16 bits, 32
     bits,   and   64   bits   of   data,    respectively.    The
     pci_config_put8(),  pci_config_put16(),  pci_config_put32(),
     and pci_config_put64() functions write 8 bits, 16  bits,  32
     bits, and 64 bits of data, respectively. The offset argument
     must be a multiple of the datum size.


     Since th  PCI Local Bus Configuration space  is  represented
     in  little endian data format, these functions translate the
     data from or to native host format to or from little  endian
     format.


     pci_config_setup(9F) must be called  before  invoking  these
     functions.

RETURN VALUES
     pci_config_get8(),  pci_config_get16(),  pci_config_get32(),
     and  pci_config_get64()  return the value read from the  PCI
     Local Bus Configuration space.

CONTEXT
     These routines can be called from user, kernel, or interrupt
     context.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:
