PLEASE, PLEASE HELP - Compile time error message

[cpptutor2000]

Could someone please help me? I have the following C struct.
typedef struct
_FIREWALL_RULE_ INFO
{
ULONG Precedence;
BOOL bEnabled;
BOOL bLoggingEnabled ;
BOOL bAllowFragments ;
BOOL bAllowInbound; /* only used
if 'SohoFirewallMo del' is enabled */
BOOL bAllowOutbound; /* only used
if 'SohoFirewallMo del' is enabled */
ULONG SessionTimeout; /* override
the session timeout value, in minutes */

ULONG Action;
BOOL bAnyService;
char
ServiceName[BOND_SERVICE_NA ME_SIZE ];

BOOL bSrcAllIpAddrs;
BOND_ADDRESS_PO OL SrcIpAddrPool;
BOOL bDstAllIpAddrs;
BOND_ADDRESS_PO OL DstIpAddrPool;

BOOL bBwmEnabled;
ULONG BwmType;
ULONG GuaBandwidthInK bps;
ULONG MaxBandwidthInK bps;
ULONG Priority;

BOND_ADDRESS_GR OUP SrcIpAddrGroup; /* this field
is for internal use only */
BOND_ADDRESS_GR OUP DstIpAddrGroup; /* this field
is for internal use only */
}
FIREWALL_RULE_I NFO, *PFIREWALL_RULE _INFO;

I get the following compile time error message, while compiling a
function that clones a FIREWALL_RULE_I NFO struct.

request for member `MaxBandwidthIn Kbps' in something not a structure
or union

Could someone please point out what I might be doing wrong? Thanks in
advance for your help.

Missing are definitions for BOOL, ULONG, BOND_ADDRESS_PO OL,
BOND_SERVICE_NA ME_SIZE, BOND_ADDRESS_GR OUP

Missing is the bit of code where you try to use it.

But, upon donning my Karnak hat, I can easily see that you have made a
mistake in your code somewhere.

Perhaps at that point, you have something like

thisthing.MaxBa ndwidthInKbps

and it is complaining because thisthing is not a structure or union.
If, for example, thisthing was a -pointer- to a structure then
you would use thisthing->MaxBandwidthIn Kbps instead of
thisthing.MaxBa ndwidthInKbps

(Given your comment about the function cloning the struct, your
code might have thisthing->MaxBandwidthIn Kbps
except that instead of thisthing being a pointer to the
structure, you have it as a pointer to a pointer to the structure,
needing (*thisthing)->MaxBandwidthIn Kbps )

What you're doing wrong is failing to show us the code that causes the error.
You say you have a function that "clones" (what exactly does that mean?) a
FIREWALL_RULE_I NFO struct. The compiler isn't complaining about the function;
it's complaining about some specific construct in the function. And it's
telling you (by showing the line number) exactly which construct it doesn't like
-- but you're not telling us.

Always show the *exact* code that produces an error, along with the *exact*
error message. Copy-and-paste both; don't try to summarize or re-type.

The above declares a type "struct _FIREWALL_RULE_ INFO" (which is unwise;
identifiers starting with "_" and an uppercase letter are reserved to the
implementation) . It declares "FIREWALL_RULE_ INFO" as an alias for this type,
and "PFIREWALL_RULE _INFO" for "pointer to struct _FIREWALL_RULE_ INFO".

My guess (and it's only a guess) is that you have something of type
"PFIREWALL_RULE _INFO", and you're trying to apply ".MaxBandwidthI nKbps" to it.
For example:

PFIREWALL_RULE_ INFO ptr; /* ptr is a pointer to struct */
...
ptr.MaxBandwidt hInKbps /* ptr is a pointer, not a struct */

Either the prefix needs to be of type FIREWALL_RULE_I NFO, or you need to use the
"->" operator instead of the "." operator.

This illustrates one reason why it's almost always a bad idea to use a typedef
for a pointer type. If you simply declared your pointers as type
"*FIREWALL_RULE _INFO", it would be more obvious that they're pointers.

(I also question the wisdom of a typedef like "ULONG". If you mean unsigned
long, just use unsigned long. If there's any possibility that ULONG could be
something other than unsigned long, then ULONG is a lousy name.)

I have rewritten your struct into C and provided both a clone function
and a main() driver. Compare your code (which you have kept secret) to
these.

memcpy(out, in, sizeof *out);
return out;

int main(void)
{

"MaxBandwidthIn Kbps in copy (*new) structure: %lu\n",
