各位高手好!!! 想請益，我自己在寫C Socket 時我有Server-Cliner連線，當Server send 1個byte資料時過一段時間Client才收到，又有時候會一傳送馬上收到!!! 還有另外一種狀況是，我 recv 速度很快收到好幾筆資料後(正常應該要這樣子) 但又卡住一陣子，又感覺順了連續收到好幾筆，之後又卡住一段時間沒收到東西之後又收到連續幾筆後又卡住了!!! 請問有這種經驗的大大嗎可以分享一下大概是哪方面出了問題以下提供我自己寫的有怪怪的地方請指正因為是這方面新手都剪剪貼貼!! Server 端 CODE 網址 http://codepad.org/CxpgQkSH Client 端 CODE 網址 http://codepad.org/yoinQcP0 以下為Client端 Code //--------------------------------- for(;;){ if((sockfd = socket(AF_INET, SOCK_STREAMNC, IPPROTO_TCP)) < 0)goto leave; bzero( &serv_addr, sizeof(struct sockaddr_in) ); serv_addr.sin_family = AF_INET; serv_addr.sin_port = htons(2400); serv_addr.sin_len = sizeof( serv_addr ); serv_addr.sin_addr.s_addr = inet_addr(SERVIP); testarg=2; if(connect(sockfd, (PSA)&serv_addr, sizeof(serv_addr)) != 0)goto leave; Slavetimeout.tv_sec = 0 ; Slavetimeout.tv_usec = 5 ; setsockopt (sockfd, SOL_SOCKET, SO_RCVTIMEO, (char *)&Slavetimeout,sizeof(Slavetimeout)); setsockopt (sockfd, SOL_SOCKET, SO_SNDTIMEO, (char *)&Slavetimeout,sizeof(Slavetimeout)); for(;;){ if( recv( sockfd, clientflagC, 1, 0 ) <= 0 )goto leave ; if( recv( sockfd,TraceObjectMC, 1, 0 ) <= 0 )goto leave ; if( send( sockfd,TraceObjectSC, 1, 0 ) <= 0 )goto leave ; if(clientflagC[0]==2){ //同步控制----------------------- SynTimeC[0]=2; if( send( sockfd, SynTimeC, 1, 0 ) <= 0 )goto leave ;//連線建立準備同步 *Clientptr=0; clientflagC[0]=0; goto leave; }//end2 if(clientflagC[0]==3){ if(SendObjArgindexCount<= RSendObjArgindexCount){ SendObjArg[0]=RSendObjArg[SendObjArgindex][0]; SendObjArg[1]=RSendObjArg[SendObjArgindex][1]; SendObjArg[2]=RSendObjArg[SendObjArgindex][2]; if( send( sockfd, SendObjArg, 3, 0 ) <= 0 ) { goto leave ; } SendObjArgTime[0]=RSendObjArgTime[SendObjArgindex][0]; SendObjArgTime[1]=RSendObjArgTime[SendObjArgindex][1]; SendObjArgTime[2]=RSendObjArgTime[SendObjArgindex][2]; if( send( sockfd, SendObjArgTime, 3, 0 ) <= 0 ) { goto leave ; } SendObjArgXY[0]=RSendObjArgXY[SendObjArgindex][0]; SendObjArgXY[1]=RSendObjArgXY[SendObjArgindex][1]; SendObjArgXY[2]=RSendObjArgXY[SendObjArgindex][2]; if( send( sockfd, SendObjArgXY, 3, 0 ) <= 0 ) { goto leave ; } SendObjArgindexCount++; if(SendObjArgindex<99)SendObjArgindex++; else SendObjArgindex=0; } }//end 3 } leave: shutdown(sockfd,2); fdClose( sockfd ); sockfd = INVALID_SOCKET; //TaskBlock( TaskSelf() ); //fdCloseSession( (HANDLE)TaskSelf() ); }//end for 排版有點爛!! 抱歉困擾我好久希望大大指點!!! 或私下教我感謝!~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 36.224.76.92
