The value associated with the selected option is returned in the buffer optval. Options affect socket operations, such as the packet routing and OOB data transfer. Options can exist at multiple protocol levels, but they are always present at the uppermost socket level. The getsockopt function retrieves the current value for a socket option associated with a socket of any type, in any state, and stores the result in optval. The option is unknown or unsupported by the indicated protocol family. The level parameter is unknown or invalid. One of the optval or the optlen parameters is not a valid part of the user address space, or the optlen parameter is too small. A successful WSAStartup call must occur before using this function. If no error occurs, getsockopt returns zero. The optname value must be a socket option defined within the specified level, or behavior is undefined. Other related and required information if any not available in no. The story was discussed at Winsock introduction story.

Writing a protocol from scratch is a big task. If you want a null terminator you have to add one yourself.

For getting the message from the client by the server I use the code below. How to get the exact message from recv in winsock programming? Ask Question. It might contain more than one message, or just the start of one. Note that what you receive might not be a single "message", especially if you're uses a stream protocol like TCP. You can add a terminator yourself, if you know the message won't contain the termination character. The result tells you how many bytes were received. Since recv might not receive as many bytes as you told it, you typically use a function like this to receive specified number of bytes.
