In lieu of using "long long" and "unsigned long long" in my code, I'm
trying to use the more compact "SInt64" and "UInt64" both of which
the compiler seems to be aware of , but when I try to give UInt64 a
large constant hex value such as 0xFFFFFFFFFFFFFFFF, the complier
complains that "integer constant is too large for "long" type." I
searched for the definition of UInt64 and found it in MacTypes.h
where it is defined as "typedef unsigned long long UInt64" so why
does the compiler not allow the maximum hex value? Is there some
undocumented upper limit to long long values?
Check the compiler support for big constants. By default, these
constants are integers (the compiler, at the time the constant is
interepreted, does not and cannot know you will store it into a long
or even long long), and thus self-evidently too big.
You'll have to use some suffix, like 0xFF...FFull (or something), to
let the compiler know the constant is long long AND unsigned, too. At
the moment, I don't recall the proper suffix though, sorry.
Adding "ull" suffix did the trick. Thanks
Ken
