- Can't figure this one out.

I have a define which I am using to define a GUID, like this.
#define CYPRESS_DEVICE_GUID {0x36FC9E60L, 0xC465, 0x11CF, {0x44, 0x45,
0x53, 0x54, 0x00, 0x00, 0x00, 0x00}}
This works FINE in some files but fails in others. I get an error : "
Syntax Error '{' where it is being used.
any ideas?

I dislike #define for precisely this reason -- because the compiler
provides no typechecking that you've used it in the correct way
everywhere. Instead I use this:
const CLSID CypressCLSID = {0x36FC9E60L, 0xC465, 0x11CF, 0x44, 0x45,
0x53, 0x54, 0x00, 0x00, 0x00, 0x00};

Because it is in the format of an initializer, this will only be
usable in a definitions, such as:
CLSID cypress = CYPRESS_DEVICE_GUID;
You wont be able to pass it to functions requiring a GUID or use it in
any other context.

I'd have to pass a pointer to it?
Thanksagain.

You'll ned to, as Lucian mentioned, create an actual instance of the
GUID, as a variable, and pass a pointer to that.

Sorry.. I took your post to imply that I could not pass the CLSID to
anything else..
of course you can not pass a pointer to a #define.
Or at least it hasn't worked yet in my 25 years of programming.

Sorry, I wasn't clear. When I said "you wont [sic] be able to pass it

declared GUID.
My apologies.
