GETLOGIN(3) GETLOGIN(3) NAME getlogin - get login name SYNOPSIS char *getlogin() DESCRIPTION Getlogin returns a pointer to the login name as found in /etc/utmp. It may be used in conjunction with getpwnam to locate the correct password file entry when the same userid is shared by several login names. If getlogin is called within a process that is not attached to a typewriter, it returns NULL. The correct procedure for determining the login name is to first call getlogin and if it fails, to call getpwuid. FILES /etc/utmp SEE ALSO getpwent(3), getgrent(3), utmp(5), getuid(2) DIAGNOSTICS Returns NULL (0) if name not found. BUGS The return values point to static data whose content is overwritten by each call.
