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.
