For processes1 and2 , the recv function is blocking , which means that the program will wait until it receives a message with tag ID9 from process0 .

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。

When the application calls recv or WSARecv , the data is copied from AFD . SYS \'s buffers to the application-provided buffer .

当应用程序调用recv（）或WSARecv（）函数时，数据将从内部缓冲拷贝到应用程序提供的缓冲区。

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。

It is not enough to just use read ( 2 ) and write ( 2 ), or recv ( 2 ) or send ( 2 ), the moment your socket becomes non-blocking .

当您的套接字变成非阻塞时，仅使用read（2）和write（2），或recv（2）或者send（2）是不够的。

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。
