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.
getusershell
() returns a null pointer (0) on
EOF
.
getusershell
() function appeared in
4.3BSD.
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.
