从 ANSI 转换为 Unicode
我正在使用 Visual Studio .NET 2003，并且尝试将纯 ANSI 字符编写的程序转换为独立于 Unicode/多字节字符的程序。
程序中有一个pcap_loop的回调函数，称为“got_packet”。它被定义为
void got_packet(u_char *user, const struct pcap_pkthdr *header, const u_char *cpacket)
{
USES_CONVERSION;
_TUCHAR *packet;
packet = A2T(cpacket);
...
}
但是，我收到错误消息
error C2440: 'type cast': cannot convert from 'const u_char *' to 'ATL::CA2WEX<>'
如何修复此问题？
I'm using Visual Studio .NET 2003, and I'm trying to convert a program written in purely ANSI characters to be independent of Unicode/Multi-byte characters.
The program has a callback function of pcap_loop, called "got_packet". It's defined as
void got_packet(u_char *user, const struct pcap_pkthdr *header, const u_char *cpacket)
{
USES_CONVERSION;
_TUCHAR *packet;
packet = A2T(cpacket);
...
}
However, I get the error message
error C2440: 'type cast': cannot convert from 'const u_char *' to 'ATL::CA2WEX<>'
How do fix this?

我的猜测是 ATL 不知道
u_char因此它无法选择正确的转换。试试这个：有关详细信息，请参阅
My guess is that ATL doesn't know
u_charso it can't select the correct convertion. Try this:For more information, see
