Does Microsoft visual studio 2010 support c99?

Solved c visual-studio visual-studio-2010 c99

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?

That's the 2008 edition, so not an exact duplicate. – Boardman 14/7, 2011 at 15:49

Looks like we're going to have C99 library support in Visual Studio 2013! – Lollipop 26/7, 2013 at 13:2

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

What about the printing factor I use? In C99 zd works fine for both 32 bit and 64 bit environment. – Grievance 14/7, 2011 at 5:49

Sorry, what is a "printing factor" and what is a "zd"? – Northerner 14/7, 2011 at 6:55

%zd print factor for intptr_t as %d for int – Grievance 14/7, 2011 at 8:42

Just make sure to pick the real type, rather than the "signed short" placeholder in the example. – Milkmaid 4/6, 2012 at 19:38

@Grievance That's not called a "printing factor", it's called a "conversion specifier". – Staphylo 30/6, 2013 at 8:13

It doesn't implement all of C99, but MSVC 2010 does have intptr_t: msdn.microsoft.com/en-us/library/323b6b3k%28v=vs.100%29.aspx – Hiding 21/10, 2014 at 17:22

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).
