endusershell(void);
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.
The routine getusershell() returns a null
pointer (0) on EOF.
The getusershell() function appeared in
4.3BSD.
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.
