NAME    [Toc]    [Back]

     getusershell, setusershell, endusershell -  get  legal  user
shells

SYNOPSIS    [Toc]    [Back]

     #include <unistd.h>

     char *
     getusershell(void);

     void
     setusershell(void);

     void
     endusershell(void);

DESCRIPTION    [Toc]    [Back]

     The getusershell() function returns a pointer to a legal user shell as
     defined by the system manager in the file  /etc/shells.   If
/etc/shells is
     unreadable  or  does not exist, getusershell() behaves as if
only /bin/sh
     and /bin/csh were listed in the file.

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

FILES    [Toc]    [Back]

BUGS    [Toc]    [Back]

     The getusershell() function leaves its result in an internal
static object
 and returns a pointer to that object.  Subsequent calls
to
     getusershell() will modify the same object.
