如何将static_cast与双播配合使用

Question

How can I use static_cast with casting types like that:

CString response;
resultData = (void *) (const char *) response;

where result data is type void *& .

I tried to do to this in following way:

resultData = static_cast<(void*)(const char*)>(response);
resultData = static_cast<void*>(static_cast<const char*>(response));

but it doesn't work.

Do you have any ideas?

Answer 1

You either need to cast to const void * :

resultData = static_cast<const void*>(static_cast<const char*>(response));

Or you need to use const_cast (which is needed to remove const , static_cast cannot remove it):

resultData = static_cast<void*>(const_cast<char *>(static_cast<const char*>(response)));

Note: if your resultData is void * , then the cast to void * is not needed.
