RTOS/TM4C1294NCPDT: Connecting to Server

Dear all,

I want to construct a local address structure, but location of the address can assign to domain name?

 memset(&localAddr, 0, sizeof(localAddr));
 localAddr.sin_family = AF_INET;
 localAddr.sin_addr.s_addr = ?;
 localAddr.sin_port = htons(arg0);

If i can not do this, how to search the IP address of domain name?

Thanks

BR,

Louis

Hi Louis,

I am not sure I am understanding what you are asking here. Can you provide more details please? Also which code example are you working from (so we have something to reference for context of how IP address/domain name may be received initially)?

Dear Ralph,

The example "tcpEcho_EK_TM4C1294XL_TI_TivaTM4C1294NCPDT" is used. I want to connect to specific server.

The specific server has domain name, and i want to use this domain name.

Thanks

BR,

Louis

Hi Louis,

I haven't heard of anyone connecting to a domain name with that example, my understanding is you need to use IP address. I looked up posts in both TM4C and the read-only TI-RTOS forums and came up with nothing that supported connecting to a domain name instead of an IP address.

As far as how to search for an IP address of a domain name, I am not sure but Google would be a good place to start. I hope you can understand that that sort of question is a bit beyond the scope of support for TM4C devices.

Dear Ralph,

Do the TM4C devices can connect to google server, and then we ask the ip address of domain name?

If there have some example?

Thanks

Hi Louis,

I had meant to do a Google search about how to get an IP address from knowing only the domain name...
