How do I printf an int32

I want to printf a 32 bit variable in hex (but decimal will do) but I can't figure out the printf formatting string. Is an unsigned long int the same as an int32?

See my post in this thread. It has sample code to display values
larger than a byte.

Thanks for that...
So the "%lu" string works for both 16 and 32 bit variable. Is that correct?

Regarding the other question, Is an "unsigned long int" the same as an int32?

%LU works for int16 and int32.

In CCS, a 'long' is a 16-bit variable. You have to use 'int32' to declare
a 32-bit variable.

See page 23 in the CCS manual. (page 33 in the Acrobat reader)
