VS2008 exe-VC6 dll互操作
我听说在 VS2005 和 VC6 之间传递 wchar_t 是相当危险的。 我试图从 VS2008 exe 中删除从 VC6 dll 分配的内存，它引发了断言。在参考 创建 wstring 时出现错误的指针或链接问题之后从vc6 dll开始，我在VC6 dll中添加了一个函数，该函数将用于删除内存。它解决了我的问题。
但是VS2008和VC6之间whcar_t的内部结构有什么区别吗..请帮忙..Rgrds

I heard somewhere that passing of wchar_t across VS2005 and VC6 is quite dangerous.
I tried to delete memory which was allocated from VC6 dll from VS2008 exe, and it raised assertion. After referring Bad pointer or link issue when creating wstring from vc6 dll, i added one func in VC6 dll which shall be used to delete memory. And it solved my issue.
But is there any difference between internal sturcture of whcar_t between VS2008 and VC6.. Please help..
Rgrds,

首先，VC6 没有
wchar_t类型。不过，两者都是 16 位类型，因此不会造成重大问题。这可能与您使用malloc()和free()遇到的问题无关，它们适用于原始的、无类型的内存。VC6 didn't have a
wchar_ttype, to start with. However, on both it's a 16 bits type, so that shouldn't cause major issues. It's likely unrelated to the problems you have withmalloc()andfree(), which work on raw, untyped memory.
