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.
