H A Dmsg_zerocopy.rst67 当应用程序向 send 系统调用传递未定义的标志时，内核通常会宽容对待。默认情况下，它会简单地忽略
79 对 send（或 sendto、sendmsg、sendmmsg）本身的改动非常简单。只需传递新的标志即可。
83 ret = send(fd, buf, sizeof(buf), MSG_ZEROCOPY);
101 MSG_ZEROCOPY 标志的 send 调用成功发送数据时，计数器都会增加。如果调用失败或长度为零，
108 下面的代码片段展示了 API 的使用。在最简单的情况下，每次 send 系统调用后，都会对错误队列
128 这个示例仅用于演示目的。在实际应用中，不等待通知，而是每隔几次 send 调用就进行一次非阻塞
132 被读取。然而，零拷贝通知具有零错误代码，因此不会阻塞 send 和 recv 调用。
H A Dtimestamping.rst90 调用之间嵌入 send() 调用来选择性地为数据包子集请求时间戳（例如，用于采样），
114 可以通过从 send() 之前立即获取的用户空间时间戳中减去此时间戳来计算。在
122 测量结果，因为时间戳是在send()调用时缓冲区中的所有数据（包括该缓冲区）
158 时间戳会以与原始send()调用不同的顺序排队到错误队列中。如此一来，仅根据
159 时间戳顺序或 payload（有效载荷）检查，并不总能将时间戳与原始send()调用
162 此选项在 send() 时将每个数据包与唯一标识符关联，并与时间戳一起返回。
297 可能跨段，任何段可能合并（可能合并先前分段缓冲区关联的独立 send() 调用）。段
