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？

Answer 1

如果它是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;

希望这可以帮助.
