Thread: Get the size of a generic type

Oh no, if you have the size, it's no problem at all. The computer memory is just raw bytes - the computer itself doesn't care about the type. The compiler only does to simplify things for YOU, the programmer.
You can allocate a certain number of bytes with type char, then use things such as memcpy to copy over the contents of the old memory.
I can't say exactly how because I don't understand exactly what you're trying to do.

By passing this function a pointer from an already dynamically allocated memory block (using malloc, calloc, realloc, etc) you can get the size of that allocated memory block (in bytes) utilizing this function.

However, it is a Microsoft-specific extension.

Usually things starting with an underscore are compiler specific.

BTW, are there a lot of Canadians in Ontario, CA?
That really confused the hell out of me when I received a package from there, until I figured out the CA meant California not Canada.

LOL! OK, well here's the Ontario, CA I thought you were talking about.
I wonder how many other cities there are in California named after Canadian provinces?
