GETLOGIN(3)                Library Functions Manual                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 type-
       writer, it returns NULL.  The correct  procedure  for  determining  the
       login  name  is  to  first  call  getlogin  and  if  it  fails, to call
       getpw(getuid()).

FILES
       /etc/utmp

SEE ALSO
       getpwent(3), getgrent(3), utmp(5), getpw(3)

DIAGNOSTICS
       Returns NULL (0) if name not found.

BUGS
       The return values point to static data whose content is overwritten  by
       each call.
