Actually i am trying to give you a hint as to how you can do it.
i use gcc (over Linux) and it works fine for me.
As you can see from the error-list
"samp.c", line 4: warning: volatile is a keyword in ANSI C
it means that yr compiler is recognizing 'volatile'.
you need to look into yr compiler's manual how to use it.

Hi,
I was getting the following error when I tried to compile the code in a
program <samp.c>.
"samp.c", line 4: warning: volatile is a keyword in ANSI C
"samp.c", line 4: undefined symbol: volatile
"samp.c", line 4: syntax error before or at: unsigned
"samp.c", line 5: undefined symbol: address
"samp.c", line 6: cannot dereference non-pointer type
"samp.c", line 7: cannot dereference non-pointer type
I am using SUN Solaris's "cc" compiler.
Regards,
Ibrahim

Dear Nayeem,
I suppose that you are trying to do the access using C.
In C, you can read/write to a hardware location as follows
volatile unsigned int* address;
int k;
address = 0xff00; //assing adrs value
*address = 5; //write to adrs
k = *address; //read from adrs
I hope this helps.
