NAME
     getusershell, setusershell, endusershell - get legal user
     shells

SYNOPSIS
     char *getusershell()

     setusershell()

     endusershell()

DESCRIPTION
     getusershell returns a pointer to a legal user shell as
     defined by the system manager in the file /etc/shells.  The
     full path name of legal shells are listed in this file, one
     per line.  If /etc/shells does not exist, the two standard
     system shells /bin/sh and /bin/csh are returned.

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

FILES
     /etc/shells

DIAGNOSTICS
     The routine getusershell returns a null pointer (0) on EOF
     or error.
