How to call linux pci bios

[phecda]

Dear sir:
       I want to write a program in Kernel2.2.4, to call pci bios system like 
pcibios_present(),pcibios_find_device(....),but I can not find bios32.h,and compiler 
can't find above function.

ex:
    #include <linux/config.h>
    #include <linux/fs.h>
    #include <linux/pci.h>
    #include <linux/bios32.h> ---->can't find it

main()
{
    #ifdef CONFIG_PCI
       printf("PCI CONFIG OK\n");
       retv = pcibios_present();
......
    #else
       printf("PCI CONFIG not OK\n");
    #endif    
}

     can you tell me why? thanks

Victor Fan....
