NAME

     pcibios_read_config_dword - read a double word of data  from
     the configuration space of the PCI bus

SYNOPSIS

     #include <linux/bios32.h>

     int pcibios_read_config_dword (unsigned char  bus,  unsigned
     char device_fn,unsigned char where, unsigned int * value);

DESCRIPTION

     The pcibios_read_config_dword function reads a  double  word
     from the configuration space of the PCI bus.  The bus can be
     specified with the bus parameters.  The  device_fn  paramter
     determines  which  ?  to use.  where is set to the ?.  After
     the call is made, value points to the value that was read.

RETURN VALUE

     The return value is taken from the PCI controller in  a  way
     that I'm not quite sure of.

     If the PCI system is unavailable, PCIBIOS_FUNC_NOT_SUPPORTED
     is returned.

AVAILABILITY

     Linux 1.0?
