*sigh* HELP HELP HELP

[Abraham vd Merwe]

Hi!

Maybe somebody can help here. I've been struggling with this for the past
half an hour and I can't figure out what's wrong:

I'm doing a MEMGETREGIONINFO ioctl() as such:

------------< snip <------< snip <------< snip <------------
static int getregions (int fd,struct region_info_user *regions,int *n)
{
   int i,err;
   err = ioctl (fd,MEMGETREGIONCOUNT,n);
   if (err) return (err);
   for (i = 0; i < *n; i++)
     {
        regions[i].regionindex = i;
        fprintf (stderr,"%d: regions[%d].regionindex =
%d\n",__LINE__,i,regions[i].regionindex);
        err = ioctl (fd,MEMGETREGIONINFO,regions[i]);
        if (err) return (err);
     }
   return (0);
}
------------< snip <------< snip <------< snip <------------

which in turn I call as such:

------------< snip <------< snip <------< snip <------------
   static struct region_info_user region[1024];

.
.
.

   err = getregions (fd,region,&n);
   if (err < 0)
     {
        perror ("MEMGETREGIONCOUNT");
        return;
     }
------------< snip <------< snip <------< snip <------------

When I run the test program I get:

------------< snip <------< snip <------< snip <------------
root at tinystor:~# ./mtd_debug info
43: regions[0].regionindex = 0
MEMGETREGIONCOUNT: Bad address
root at tinystor:~#
------------< snip <------< snip <------< snip <------------

I can't find a problem with the user program nor with my driver (I can print
the mtd->eraseregions structures from the chip driver and it works perfectly)

Any ideas? What am I doing wrong?

You never learn anything by doing it right.
