NAME    [Toc]    [Back]

     getusershell, setusershell, endusershell - get valid user shells

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     char *
     getusershell(void);

     void
     setusershell(void);

     void
     endusershell(void);

DESCRIPTION    [Toc]    [Back]

     The getusershell() 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, getusershell()
     behaves as if /bin/sh and /bin/csh were listed.

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

FILES    [Toc]    [Back]

     /etc/shells

DIAGNOSTICS    [Toc]    [Back]

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

HISTORY    [Toc]    [Back]

     The getusershell() function appeared in 4.3BSD.

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.
