To my amazement I just discovered that the C99 stdint.h is missing from MS Visual Studio 2003 upwards. I'm sure they have their reasons, but does anyone know where I can download a copy? Without this header I have no definitions for useful types such as uint32_t, etc.

Turns out you can download a MS version of this header from:
https://github.com/mattn/gntp-send/blob/master/include/msinttypes/stdint.h
A portable one can be found here:

Thanks to the Software Ramblings blog.
NB: The Public Domain version of the header, mentioned by Michael Burr in a comment, can be find as an archived copy here. An updated version can be found in the Android source tree for libusb_aah.

A public domain (not an MIT/BSD license - you don't even need to keep a copyright attribution around) stdint.h for MSVC (a slightly modified version from MinGW): snipplr.com/view/18199/stdinth

Modified the original answer but: github.com/mattn/gntp-send/blob/master/include/msinttypes/… the svn link is dead
Update: Visual Studio 2010 and Visual C++ 2010 Express both have stdint.h. It can be found in C:\Program Files\Microsoft Visual Studio 10.0\VC\include

As well as <cstdint> for C++ users who like it in
std::.Just define them yourself.
#ifdef _MSC_VER
typedef __int32 int32_t;
typedef unsigned __int32 uint32_t;
typedef __int64 int64_t;
typedef unsigned __int64 uint64_t;
#else
#include <stdint.h>
#endif

Am I missing something or shouldn't it be typedef unsigned __int64 uint64_t; ?
Niklas
And to use literal uint64_t values it is useful to
#define U64(u) (u##ui64) on Windows and to #define U64(u) (u##ULL) otherwise.Visual Studio 2003 - 2008 (Visual C++ 7.1 - 9) don't claim to be C99 compatible. (Thanks to rdentato for his comment.)

Boost contains cstdint.hpp header file with the types you are looking for: http://www.boost.org/doc/libs/1_36_0/boost/cstdint.hpp

boost is C++, the question is on C99
Nemanja Trifunovic
It is not clear - he is asking about a C99 header in Visual Studio, without specifying which language he is using. In any case it can't be C99 because Microsoft does not support it.
jww
OP wants a copy of
<stdint.h>, not a Boost header.Microsoft do not support C99 and haven't announced any plans to. I believe they intend to track C++ standards but consider C as effectively obsolete except as a subset of C++.
New projects in Visual Studio 2003 and later have the "Compile as C++ Code (/TP)" option set by default, so any .c files will be compiled as C++.
