why does this generate a C2219?

[andrey the giant]

This generates a C2219 though the standard (C99) says it shouldn't.

typedef __int8 *i8p;
void foo(i8p __restrict bar){};

Is __restrict limited to explicit (T *) pointers as opposed to typedef-
ed (see example) ones?

How about using this instead?
typedef __int8 * __restrict i8p;
void foo(i8p bar){};

FYI, Visual C++ does not implement C99.

Yeah, it only implements bits and pieces the Microsoft Way (TM).

Qouting MSDN:

"__restrict is similar to restrict from the C99 spec"


except that it doesn't work on implicit (typedef) pointer types

Which compiler and version are you using?

Note that VC++ 2008 and earlier do not implement C99, only C89/C90.

Neither, apparently, does VC++ 2010.

This page on VC++ 2010:

http://msdn.microsoft.com/en-us/library/abx4dbyh(VS.100).aspx

says:

"This version of Visual C++ is not conformant with the C99 standard."

Some discussion of the rationale can be found in this blog:
