Windows
This describes the D implementation for 32 bit Windows systems. Naturally, Windows specific D features are not portable to other platforms.
Instead of the:
#include <windows.h>
of C, in D there is:
import core.sys.windows.windows;
Calling Conventions
In C, the Windows API calling conventions are __stdcall. In D, it is simply:
extern (Windows)
{
/* ... function declarations ... */
}
The Windows linkage attribute sets both the calling convention and the name mangling scheme to be compatible with Windows.
For functions that in C would be __declspec(dllimport) or __declspec(dllexport), use the export attribute:
export void func(int foo);
If no function body is given, it's imported. If a function body is given, it's exported.
