     LOGNAME(S)                UNIX System V                LOGNAME(S)



     Name
          logname - return login name of user

     Syntax
          char *logname( )

     Description
          The logname function returns a pointer to the null-
          terminated login name; it extracts the LOGNAME environment
          variable from the user's environment.

          This routine is kept in /lib/libPW.a and must be linked with
          the -lPW flag.

     Files
          /etc/profile

     See Also
          getenv(S), profile(M), environ(M), env(C), login(M).

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

          This method of determining a login name is subject to
          forgery.

     Standards Conformance
          logname is conformant with:
          AT&T SVID Issue 2, Select Code 307-127;
          and The X/Open Portability Guide II of January 1987.
