Question

D2语相当于dec(出口)

I have the D2 DLL linkage example code up and running. Exporting functions, both in dmd s mangled name space as well as well as in standard u-mangled "C" name space, works like a charm. But I m running into uncharted waters regarding the sharing of a (global) int Variable between DLL s as well as the main exe program... I ve checked the DLL symbol table with depends22_x86 and while I made a point of using the export directive just before the Var s declaration, it does not show up in the DLL s table, while functions do. Can one export Varibles to be visible in a DLL with the Digital Mars dmd tool chain?

Answer 1

This was a bug in the compiler (Bugzilla 10059). The following code should work now.

export __gshared int foo;

Answer 2

或许你们可以做Ralph Tandetzky所说的话,但在固定单元的导师中。你们胜过,必须明确称职,所有符号都将装上。或许也可以分享。

Answer 3

作为一种工作,如果出口或进口全球变数不作工作,则写上表格的包装功能。

Type variable;

extern(C) Type * getGlobalVariable()
{
    return &variable;
}

如果想从D到C出口的话。
