RECV-的意思|示意

In this case, you iterate through the contents of the recv aggregate, sum the packet lengths for each tuple (device name, PID, and process name), then emit this data.

在本例中，您将遍历recv聚合的内容、为每个元组(设备名、PID和进程名)相加包的长度，然后发出该数据。

Note the use of ACE_INET_Addr in the recv method: This helps capture the peer computer from which the data was being transmitted.

注意recv方法中对ACE_INET_Addr的使用方法：这有助于捕捉正在传输数据的对等计算机。

While recv (a library function used by the process), recvfrom, and recvmsg operate only on socket descriptor, read and readv can operate on any kind of descriptor.

尽管recv(进程使用的库函数)、recvfrom和recvmsg仅可以对套接字描述符操作，但read和readv可以对任何种类的描述符操作。

For processes 1 and 2, the recv function is blocking, which means that the program will wait until it receives a message with tag ID 9 from process 0.

对于进程1和2,recv函数被阻塞，这意味着程序会等待，直到从进程0收到标签id为9的消息。
