+.SH DESCRIPTION
+.B getln
+reads a line of characters, terminated by a
+.I sep
+character,
+from
+.IR ss .
+It returns the line in
+.I sa
+and sets
+.I match
+to 1.
+
+If
+.B getln
+sees end-of-input before it sees
+.IR sep ,
+it returns the partial line in
+.I sa
+and sets
+.I match
+to 0.
+
+.B getln
+normally returns 0.
+If it runs out of memory,
+or encounters an error from
+.IR ss ,
+it returns -1,
+setting
+.B errno
+appropriately.
