GETUSERSHELL(3)	       FreeBSD Library Functions Manual	       GETUSERSHELL(3)

NAME
     getusershell, setusershell, endusershell -- get legal user	shells

SYNOPSIS
     #include <unistd.h>

     char *
     getusershell(void);

     void
     setusershell(void);

     void
     endusershell(void);

DESCRIPTION
     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	/bin/sh	and
     /bin/csh were listed in the file.

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

FILES
     /etc/shells

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

SEE ALSO
     shells(5)

HISTORY
     The getusershell()	function appeared in 4.3BSD.

BUGS
     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.
