+/*
+ * File: condvar3.c
+ *
+ * Test Synopsis:
+ * - Test basic function of a CV
+ *
+ * Test Method (Validation or Falsification):
+ * - Validation
+ *
+ * Requirements Tested:
+ * - 
+ *
+ * Features Tested:
+ * - 
+ *
+ * Cases Tested:
+ * - 
+ *
+ * Description:
+ * - The primary thread takes the lock before creating any threads.
+ *   The secondary thread blocks on the lock allowing the primary
+ *   thread to enter the cv wait state which releases the lock.
+ *   The secondary thread then takes the lock and signals the waiting
+ *   primary thread.
+ *
+ * Environment:
+ * - 
+ *
+ * Input:
+ * - None.
+ *
+ * Output:
+ * - File name, Line number, and failed expression on failure.
+ * - No output on success.
+ *
+ * Assumptions:
+ * - 
+ *
+ * Pass Criteria:
+ * - pthread_cond_timedwait returns 0.
+ * - Process returns zero exit status.
+ *
+ * Fail Criteria:
+ * - pthread_cond_timedwait returns ETIMEDOUT.
+ * - Process returns non-zero exit status.
