recv meaning in Chinese

Examples
- Btw : if you want to call recv ( ) with the maximal length of return _ msg , please use sizeof ( return _ msg ) instead of strlen ( return _ msg )
但是就是不明白为什么如果接受的长度大于了实际返回的长度就可能出现我上述的那种情况呢（好像不是所有的时候都那样） ！ - Socket function mainly realizes setting up and initializing service unit socket , initializing service unit and service unit serial and so on . bind funcion primarily binds local address and port for the socket . listen function is to evaluate the max length of server ’ s listening queue . connect function and accept function set aside rate ahead , infrom user ’ s request of establishing virtual circuit to suna , cooperate with suna to establish the connection between client and server , return the result . we make use of three handshake with data protocol and virtual circuit mode , in this way , when we translate data , we can look up communication course according to virtual circuit number , at the same time , there aren ’ t source ip address and port , end ip address and port in the head of data package , the speed of translating data advances in a certain extent . send function and recv function is to send data collaborating with suna , and copy data from the receiving queue of socket to user ’ s buffer . close function cooperate
Socket ( )函数实现创建、初始化服务元套接字,初始化服务元及服务元序列等。 bind ( )函数为套接字绑定本地地址和端口号。 connect ( )和accept ( )函数主要是根据用户要求预留带宽,将用户的建立虚电路请求转达给服务元网络体系,协作服务元网络体系采用捎带数据的三次握手协议建立虚电路,并告诉用户处理结果,一方面,捎带数据的三次握手协议在一定程度上可提高数据传输速度;另一方面,采用虚电路方式,使得数据通信可直接根据虚电路号查找相应的通信进程,而且数据包的包头中省去了源ip地址、端口号和目的ip地址、端口号,提高了数据传输速率。
