GETLOGIN(3)             GENIX Programmer's 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
           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)

      DIAGNOSTICS
           Returns NULL (0) if name not found.

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