问题
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.
回答1:
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.
回答2:
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

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
回答4:
Visual Studio 2003 - 2008 (Visual C++ 7.1 - 9) don't claim to be C99 compatible. (Thanks to rdentato for his comment.)
回答5:
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
回答6:
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++.
