pci_find_device() issue

Hi,

I’m trying to detect several devices with the same vendorID and deviceID.
To do that I call pci_find_device(), but every time this function is
terminated
by the SIGSEGV signal.

What can be a reason ?
Below is source code.

Regards,
Jacek


#include <stdlib.h>

#include <stdio.h>

#include <hw/pci.h>

#include <sys/neutrino.h>



#define VendorID 0x1011

#define DeviceID 0x9

#define max_index 10



int main(int argc, char *argv[]) {

int phdl,i;

unsigned* dev_func, *bus;

phdl = pci_attach(0);

if( phdl == -1 ) {

fprintf( stderr, “Unable to initialize PCI\n” );

return EXIT_FAILURE;

}

for (i=0;i<max_index;i++){

if (pci_find_device(DeviceID,VendorID,i,bus,dev_func)== PCI_SUCCESS)

printf ("\n Found adapter: VendorID=0x%x, DeviceID=0x%x, pci_index=%d
\n",VendorID,DeviceID,i);

}

pci_detach( phdl );


return EXIT_SUCCESS;

}

Now, with these two modifications is ok:

unsigned dev_func,bus;
…

if (pci_find_device(DeviceID,VendorID,i,&bus,&dev_func)== PCI_SUCCESS)
