Thread: Error while creating socket....

Hi,

Following is the code i have been checking...

Code:

void createsocket()
{
	struct sockaddr_in server_addr;  
	unsigned int port = 0;	
	char server_ip[255];

	if ((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
		perror("Socket");
		exit(1);
	}
	memset( &server_addr , 0 , sizeof(server_addr) );  
	 
	server_addr.sin_family = AF_INET;  
	CheckIPAddress(server_ip);
	CheckPort(&port);  //This reads the value from flash file     
             server_addr.sin_addr.s_addr = inet_addr(server_ip);  

             server_addr.sin_port = htons(27015); //While hardcoding the port establishs connection    
	server_addr.sin_port = htons(port); //This gives an error failed to connect           
	
   //Now connect to remote server  
    if(connect( sock , (const struct sockaddr*) &server_addr , sizeof(server_addr) ) < 0)  
    {  
  
    }  

}

1. I have a issue while assiging port to htons() ---> if hardcoded it seems to establish the connection.
2. If the same is replace with a read value from a file. Connection established fails.............

Am I doing something wrong with the way the variable is defined.
I am using an unsigned int -----> while the htons() takes unsinged int.
But value read from the file is stored in an int variable.
Is this the problem?

Let me know where i am wrong?

Thanks in advance!!!!!!!

yes.............Its returning the same as the one which is hardcoded(As i have written the hardcoded value to file).
