+.SH DESCRIPTION
+.B getln2
+reads a line of characters, terminated by a 
+.I sep
+character,
+from
+.IR ss .
+
+The line is returned in two pieces.
+The first piece is stored in
+.IR sa .
+The second piece is
+.IR cont ,
+a pointer to
+.I clen
+characters inside the
+.I ss
+buffer.
+The second piece must be copied somewhere else
+before
+.I ss
+is used again.
+
+If
+.B getln2
+sees end-of-input before it sees
+.IR sep ,
+it sets
+.I clen
+to 0 and does not set
+.IR cont .
+It puts the partial line into
+.IR sa .
+
+.B getln2
+normally returns 0.
+If it runs out of memory,
+or encounters an error from
+.IR ss ,
+it returns -1,
+setting
+.B errno
+appropriately.
