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.
