NAME

6       getlogin - get login name
7

SYNOPSIS

9       char *getlogin();
10

DESCRIPTION

12       Getlogin returns a pointer to the login name as found in /etc/utmp.  It
13       may be used in conjunction with getpwnam to locate the correct password
14       file entry when the same userid is shared by several login names.
15
16       If  getlogin is called within a process that is not attached to a type‐
17       writer, it returns NULL.  The correct  procedure  for  determining  the
18       login name is to first call getlogin and if it fails, to call getpwuid.
