13-Openwrt libubox ustream

流缓冲管理,ustream_fd跟uloop_fd有什么不一样呢？ustream_fd内部其实就是uloop_fd，与fopen和open类似，fopen的内部也是open加上流缓冲管理。

struct ustream_fd {
    struct ustream stream;
    struct uloop_fd fd;
};

ustream相关的函数

void ustream_fd_init(struct ustream_fd *s, int fd)

void ustream_init_defaults(struct ustream *s)

void ustream_free(struct ustream *s)

ustream的应用在uhttpd的socket监听里面有使用到

bool uh_accept_client(int fd, bool tls)
{
    static struct client *next_client;
    struct client *cl;
    unsigned int sl; 
    int sfd;
    static int client_id = 0;
    struct sockaddr_in6 addr;

    if (!next_client)
        next_client = calloc(1, sizeof(*next_client));
