- Walter (3/7) Feb 08 2002 You can always just leave it in the C or Windows calling convention.
Walter, is it possible to add user-defined attributes to
the language - something that would conform to this in C:
#ifdef DLL
#define MYEXPORT __stdcall _export
#else
#define MYEXPORT __cdecl
#endif
...
MYEXPORT void foo() { }
It could look like this:
version (DLL)
attribute MyExport = extern(Windows) export;
else
attribute MyExport = extern(D);
...
attribute(MyExport) void foo() { }
Could be helpful in writing projects that can be either
static libs or DLLs, as well as porting such (zlib!) to
D.
