getlogin() does sometimes return the wrong username, e.g.
$ ./getlogin
getlogin: per-stia
$ id
uid=1000(aagero) gid=1000(aagero) groups=1000(aagero),0(wheel),2(kmem)
That is, getlogin returns the same bogus name each time I call it. But
if I login to a new session, e.g. rlogin localhost, getlogin() returns
the same as getuid(). The user returned from getlogin is usually
logged in when this happens.
----------------
/* getlogin.c */
#include <stdio.h>
#include <unistd.h>
void main(void)
{
printf("getlogin: %s\n", getlogin());
}
