I'm working on a C program that needs to use the hostname of the computer it is running on. My current method of retrieving this is by mangling a C API like this:
char *host = new char[1024];
gethostname(host,1024);
auto hostname = std::string(host);
delete host;
Is there a portable modern C method for doing this, without including a large external library (e.g., boost)?
CodePudding user response:
No, there is no standard C support for this. You'll either have to make your own function, or get a library that has this functionality.
