? ? ? ? ? ? ? ? 并發(fā)服務(wù)端有多線程的和多進(jìn)程的，今天來(lái)看一下多線程的。線程編程可能會(huì)麻煩一點(diǎn)，其中涉及到一些同步，死鎖問(wèn)題，但是也有其優(yōu)點(diǎn)。并發(fā)服務(wù)端用的多的還是多進(jìn)程。

服務(wù)端：

#include<sys/socket.h> #include<netinet/in.h> #include <arpa/inet.h> #include <unistd.h> #include <stdio.h> #include <string.h>int main() {int sockClient = socket(AF_INET, SOCK_STREAM, 0);struct sockaddr_in addrSrv;addrSrv.sin_addr.s_addr = inet_addr("127.0.0.1");addrSrv.sin_family = AF_INET;addrSrv.sin_port = htons(8888);connect(sockClient, ( const struct sockaddr *)&addrSrv, sizeof(struct sockaddr_in));char sendBuf[100] = "123";char recvBuf[100];send(sockClient, sendBuf, strlen(sendBuf)+1, 0);printf("%s\n", sendBuf);recv(sockClient,recvBuf,sizeof(recvBuf),0);printf("recvBuf=%s\n",recvBuf);getchar();close(sockClient);return 0; }

經(jīng)過(guò)編譯，能運(yùn)行。

[mapan@localhost threadServer]$ ./server recvDate=123[mapan@localhost threadServer]$ ./client 123 recvBuf=Server has received your request!
