linux c - get server hostname?

Question

Does anyone know a function to get the hostname of the linux server? I don\'t really want to have to include any headers or compile other libraries, hoping there is a function b

Answer 1

like gethostname() ?

That's the name of the machine on which your app is running.

Or read from

/proc/sys/kernel/hostname

Update

Simple example

#include 
#include 
#include 

int main(void) {

    char hostname[1024];
    gethostname(hostname, 1024);

    puts(hostname);

    return EXIT_SUCCESS;
}
