NAME
       pcibios_read_config_dword - read a double word of data from the config‐
       uration 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?
