如何通过cpp中的套接字流式传输位图数据？

Question

I am working on a remote administration project in cpp that will stream graphic data- in bitmap object- over winsock. The winsock send and rcv function use only buffers of data type char*. How can I stream data from bitmap object over a socket?

Answer 1

Cast your buffers to char * and pass the size of the buffer in bytes as the length. Note that send() can only deal with whole bytes.
