What is the OSX, C equivalent for uint32 and uint64?

Question

I imagine this is a question that has been asked a thousand times but I can't find a straight answer.

I'm trying to port a very short, C function (initially written for Windows) to OSX, using XCode.

I've created an XCode, Terminal application project and I've copied and pasted the code into the project. XCode is giving me a bunch of errors telling me that the type uint32 and uint64 are unknown types.

What are the equivalent value types in OSX?

Answer 1

Try these ;-) UInt32 lala; UInt64 lolo;

Misread the question. If you create a terminal only project you won't be linking Cocoa/Foundation and Carbon. Within the latter UInt16/32/64 are typedef'ed.

Answer 2

What you want are the POSIX and C standard integer types. These are what are used on Mac OSX, Linux, Solaris, etc. They are uint8_t all the way through uint64_t. There are also int8_t through uint8_t.

Answer 3

uint32_t and uint64_t — both defined in stdint.h as per the C99 definition.

The others are Microsoft's proprietary solution.

Answer 4

You can use uint32_t and uint64_t by importing stdint.h.
