SYNOPSIS
     ##iinncclluuddee <>

     char *
     ggeettuusseerrsshheellll(void);

     void
     sseettuusseerrsshheellll(void);

     void
     eenndduusseerrsshheellll(void);

DESCRIPTION
     The ggeettuusseerrsshheellll() function returns a pointer to a valid user shell as
     defined by the system manager in the shells database as described in
     shells(5).  If the shells database is not available, ggeettuusseerrsshheellll()
     behaves as if /bin/sh and /bin/csh were listed.

     The ggeettuusseerrsshheellll() function reads the next line (opening the file if nec-
     essary); sseettuusseerrsshheellll() rewinds the file; eenndduusseerrsshheellll() closes it.

FILES     /etc/shells

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

SEE ALSO
     shells(5)

HISTORY     The ggeettuusseerrsshheellll() function appeared in 4.3BSD.

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