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_SUP­
       PORTED is returned.

AVAILABILITY

       Linux 1.0?
