+ * File: sockpong.c
+ *
+ * Description:
+ * This test runs in conjunction with the sockping test.
+ * The sockping test creates a socket pair and passes one
+ * socket to this test.  Then the sockping test writes
+ * "ping" to this test and this test writes "pong" back.
+ * To run this pair of tests, just invoke sockping.
+ *
+ * Tested areas: process creation, socket pairs, file
+ * descriptor inheritance.
