It is not really AIX specific, but here is a very simple example:

#include <stdlib.h>

int main ( void ) {
char *thename;
int thelen = 20, theresult;
theresult = gethostname(thename,thelen); printf("The hostname is %s and gethostname() returned %d\n",thename,theresult); exit(0);
}

Notice that gethostname() does not return the name, it puts the name in the first argument which is a pointer to an array of char. It returns a simple 0 or 1 for 'no error' or 'error' respectively.
