问题
I would like to know if Microsoft Visual Studio 2010 supports C99. If not, how can I use the standard types like intptr_t and uintptr_t?
回答1:
As far as I can tell, Visual Studio 2010 does not support C99. To use types from stdint.h, you will have to use a typedef. A cross-platform way to do this would be:
#ifdef _WIN32
typedef signed short int16_t
#else
#include <stdint.h>
#endif

Visual Studio 2010 does not support C99 syntax. stdint.h is a very common file in all C/C++ compilers, though, which does exist in a Visual C++ 10.0 installation, included with the Windows SDK (regardless of the version of Visual Studio that you use).
stdint.h can be found in:
- C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\
This file does provide a typedef for intptr_t. Feel free to use it in any C or C++ project you like.

Microsoft C does not support C99. However, MSVC 16 (what's provided with Visual Studio 2010) implements a good portion of the upcoming C++0x standard. C++0x is incorporating some of the headers from C99, such as stdint.h and inttypes.h - that's why you get some tidbits of C99 with MSVC 16.
Be thankful for small things (I wish MSVC supported a bit more of C99 when compiling straight C files).
