GETLOGIN(S) XENIX System V GETLOGIN(S)
Name
getlogin - Gets login name.
Syntax
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 user ID
is shared by several login names.
If getlogin is called within a process that is not attached
to a terminal device, it returns NULL. The correct
procedure for determining the login name is to call cuserid,
or to call getlogin and if it fails, to call getpwuid.
Files
/etc/utmp
See Also
cuserid(S), getgrent(S), getpwent(S), utmp(M)
Diagnostics
Returns NULL if name not found.
Notes
The return values point to static data whose content is
overwritten by each call.
