+the broken out fields of a line in the file \fIstream\fP.
+The first time it is called it returns the first entry;
+thereafter, it returns successive entries.
+The file referred to by
+.I stream
+must have the same format as
+.I /etc/passwd
+(see
+.BR passwd (5)).
+.P
+The \fIpasswd\fP structure is defined in \fI<pwd.h>\fP as follows:
+.P
+.in +4n
+.EX
+struct passwd {
+    char   *pw_name;       /* username */
+    char   *pw_passwd;     /* user password */
