Dear.
I just make socket program in legato platform.
It was general example code from web.
Also, It had no problem in ubuntu condition. but when I run same code in legato side
The client could not connect server side and return connection failure.
This is my window legato platform version and example code
(Legato for WP85/WP75 R16.1)
======================================================
Server side code
#define MAX 80
#define PORT 8080
#define SA struct sockaddr
void func(int sockfd)
{
char buff[MAX];
//int n;
// infinite loop for chat
for (; {
bzero(buff, MAX);
printf("\nserver function call\n");
// read the message from client and copy it in buffer
read(sockfd, buff, sizeof(buff));
// print buffer which contains the client contents
printf("From client: %s\t To client : ", buff);
sleep(3);
strncpy(buff,"Server string",100);
// and send that buffer to client
write(sockfd, buff, sizeof(buff));
// if msg contains "Exit" then server exit and chat ended.
if (strncmp("exit", buff, 4) == 0) {
printf("Server Exit...\n");
break;
}
}
}
// Driver function
void main()
{
int sockfd, connfd;
socklen_t len;
struct sockaddr_in servaddr, cli;
// socket create and verification
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd == -1) {
printf("socket creation failed...\n");
exit(0);
}
else
printf("Socket successfully created..\n");
bzero(&servaddr, sizeof(servaddr));
// assign IP, PORT
servaddr.sin_family = AF_INET;
servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
servaddr.sin_port = htons(PORT);
// Binding newly created socket to given IP and verification
if ((bind(sockfd, (SA*)&servaddr, sizeof(servaddr))) != 0) {
printf("socket bind failed...\n");
exit(0);
}
else
printf("Socket successfully binded..\n");
// Now server is ready to listen and verification
if ((listen(sockfd, 5)) != 0) {
printf("Listen failed...\n");
exit(0);
}
else
printf("Server listening..\n");
len = sizeof(cli);
// Accept the data packet from client and verification
connfd = accept(sockfd, (SA*)&cli, &len);
if (connfd < 0) {
printf("server acccept failed...\n");
exit(0);
}
else
printf("server acccept the client...\n");
// Function for chatting between client and server
func(connfd);
// After chatting close the socket
close(sockfd);
}
==============================================================
Client Side code
#define MAX 80
#define PORT_NO 8080
#define SA struct sockaddr
static int clientSocketFd;
static struct sockaddr_in servaddr;
#define IP_ADDRESS “127.0.0.1” // localhost
void func(int sockfd)
{
char buff[MAX];
//int n;
for (; {
printf("\nfunc call\n");
bzero(buff, sizeof(buff));
strncpy(buff,"client string",100);
write(sockfd, buff, sizeof(buff));
sleep(3);
bzero(buff, sizeof(buff));
read(sockfd, buff, sizeof(buff));
printf("\n");
printf("From Server : %s", buff);
if ((strncmp(buff, "exit", 4)) == 0) {
printf("Client Exit...\n");
break;
}
}
}
void main()
{
int sockfd;
struct sockaddr_in servaddr;
// socket create and varification
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd == -1) {
printf("socket creation failed...\n");
exit(0);
}
else
printf("Socket successfully created..\n");
bzero(&servaddr, sizeof(servaddr));
// assign IP, PORT
servaddr.sin_family = AF_INET;
servaddr.sin_addr.s_addr = inet_addr("127.0.0.1");
servaddr.sin_port = htons(PORT_NO);
// connect the client socket to server socket
if (connect(sockfd, (SA*)&servaddr, sizeof(servaddr)) != 0) {
printf("connection with the server failed...\n");
exit(0);
}
else
printf("connected to the server..\n");
// function for chat
func(sockfd);
// close the socket
close(sockfd);
}
Server side run correctly and never show any error code. but Client side show error return as below
Mar 25 08:41:23 | testserverclient[5937]/testServerClientComponent T=main | testServerClientComponent.c _testServerClientComponent_COMPONENT_INIT() 77 | Client Start
Mar 25 08:41:23 | testserverclient[5937] | | Socket successfully created…
Mar 25 08:41:24 | testserverclient[5937] | | connection with the server failed…
Do you have any tips ?
Thanks all.
