将char指针（char *）转换为struct

Question

我有一个结构：

//Custom packet structure.
struct UserPacket
{
 __int64 pingTime;
} CustomPacket;

我已经想出如何将它转换为char *。现在我想将char *转换回struct。有什么建议吗？

Answer 1

如果是C ++：

char* theCharPtr; // has your converted data

UserPacket* fromChar = reinterpret_cast<UserPacket*>(theCharPtr);

Answer 2

Typecast吧。以下是一些示例（两个使用类型转换）。

CustomPacket  customPacket;

char *          p = (char *) &customPacket;

CustomPacket *  pPacket    = (CustomPacket *) p;
CustomPacket *  pAlternate = &customPacket;

希望这有帮助。
