Setsockopt

Setsockopt是一个用于设置套接字选项值的函数。它可以用于设置任意类型和状态的套接字的选项值。函数原型为int setsockopt(int sockfd, int level, int optname, void *optval, socklen_t *optlen)。其中，sockfd是套接字描述符，level是套接字代码的层次（通常使用SOL_SOCKET），optname是要设置的选项名，optval是要设置的选项的值，optlen是值的长度。例如，Setsockopt(sockfd, SOL_SOCKET, SO_SNDBUF, &sendbuff, sizeof(sendbuff))用于设置发送缓冲区大小。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
