Question

I am trying to port some C which uses read() and write() functions for sending sockets. I am trying to port this to windows and it is suggested (from what I have read) to use WriteFile and ReadFile to accomplish my task.

I read according to Microsoft API documentation that WriteFile will accept a socket. But I am unsure why its not working

(Beginner C Coder)

SOCKET sock;

I set sock to a socket type

WriteFile((HANDLE *)sock, data, 17, NULL, NULL);

Now I know I am doing some thing wrong with that (HANDLE *) type cast but I get an error saying that “int cast to pointer with out a type cast” if I don’t (or something similar).

So my question is how can I send a socket using WriteFile as well as read a socket using ReadFile

WriteFile wants a handle, not a pointer to a handle. You probably want to use:

WriteFile((HANDLE)sock, data, 17, NULL, NULL);
