I want to set the name of my local host. I am using sethostname() function but I get an error as follows:
error C3861: 'sethostname': identifier not found.
Below is the code snippet:

C#

WSADATA wsa;
///Initialise winsock///
if (WSAStartup(MAKEWORD(2,2),&wsa) != 0)
   {
      //Socket Initialization Failed///
      exit(EXIT_FAILURE);
   }
 char setname[128]="Ayesha-PC";
 sethostname(setname, sizeof (setname));

Are you looking for SetComputerNameEx[^]?

Thank you for the help, but this function changes the name of PC after the system is restarted while I want to change the name as soon as the function is called.

Solution 3

According to the winsock documentation[^] there is no such function.

You probably have seen that as example in a Unix-based application. There the function sethostname exists, (although it would be called with strlen (name) as second argument, and not with sizeof (name).

For an equivalent in the Windows world, CPallini has given you already the correct link.
