DESCRIPTION
      getusershell returns a pointer to a legal user shell as defined by the
      system manager in the file /etc/shells.  If /etc/shells does not exist,
      the locations of the standard system shells, /usr/bin/csh, /usr/bin/sh,
      and /usr/bin/ksh are returned.

      getusershell reads the next line (opening the file if necessary);
      setusershell rewinds the file; endusershell closes it.

FILES
      /etc/shells
      /usr/bin/csh
      /usr/bin/ksh
      /usr/bin/sh

RETURN VALUE
      The routine getusershell returns a NULL pointer (0) on EOF or error.
