GETUSERSHELL(3) 		    Linux Programmer's Manual			  GETUSERSHELL(3)

NAME
       getusershell, setusershell, endusershell - get permitted user shells

SYNOPSIS
       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       getusershell(), setusershell(), endusershell(): _BSD_SOURCE || (_XOPEN_SOURCE &&
       _XOPEN_SOURCE < 500)

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

FILES
       /etc/shells

CONFORMING TO
       4.3BSD.
