NAME    [Toc]    [Back]

SYNOPSIS    [Toc]    [Back]

DESCRIPTION    [Toc]    [Back]

       The  getusershell()  function  returns  the  next  line	from  the file
       /etc/shells, opening the file if necessary.  The  line  should  contain
       the  pathname  of a valid user shell.  If /etc/shells does not exist or
       is unreadable, getusershell() behaves as if  /bin/sh and /bin/csh  were
       listed in the file.

       The setusershell() function rewinds /etc/shells.

       The endusershell() function closes /etc/shells.

RETURN VALUE    [Toc]    [Back]

       The getusershell() function returns a NULL pointer on end-of-file.
